Introduction Scope of Manual This instruction manual provides installation, start-up, adjustment, maintenance, and parts ordering information for the Type EZR pressure reducing regulator, the Type 112 restrictor, the 161AY Series pilot, and the 161EB Series pilot. Any accessories used with this regulator are covered in their respective instruction manuals.

Product Description

Specifications Specifications for the Type EZR regulator are found on page 2. The control spring range for the pilot is marked on the spring case of 161EB Series pilots and on the nameplate of 161AY Series pilots. Other information for the main valve appears on the nameplate.

D102600X012

The Type EZR pilot-operated, pressure reducing regulators are used for natural gas, air, or other non-

corrosive gas applications and include a Type 112 restrictor and a 161EB Series or 161AY Series pilot.

For applications that have high pressure drops, using a Type 161AYM, 161EBM, or 161EBHM monitor pilot will increase the accuracy of the regulator.

to keep the main valve diaphragm and plug assembly tightly shut off.

As long as the outlet (control) pressure is above the outlet pressure setting, the pilot valve plug or disk remains closed (figure 2). Force from the main spring, in addition to inlet pressure bleeding through the Type 112 restrictor, provide downward loading pressure

When the outlet pressure decreases below the pilot outlet pressure setting, the pilot plug or disk assembly opens. Loading pressure bleeds downstream through the pilot faster than it can be replaced through the Type 112 restrictor. This reduces loading pressure on

4

Type EZR top of the main valve diaphragm and plug assembly and lets the unbalanced force between inlet and loading pressure overcome the main spring force to open the Type EZR diaphragm and plug assembly.

As the outlet pressure rises toward the outlet pressure setting, it compresses the pilot diaphragm against the pilot control spring and lets the pilot valve plug or disk close. Loading pressure begins building on the Type EZR diaphragm and plug assembly. The loading pressure, along with force from the main spring, pushes the diaphragm and plug assembly onto the knife edged seat, producing tight shutoff.

Pilot Type Descriptions Type 161AY—Low-pressure pilot with an outlet pressure range from 6-inches w.c. to 7 psig (15 mbar to 0,48 bar).

Pilot bleeds (exhausts) downstream through the sense (control) line.

Type 161AYM—The monitor version of the Type 161AY pilot. The pilot bleed (exhaust) is isolated from the sense (control) line. This pilot is used in monitoring systems requiring an isolated pilot bleed (exhaust).

VALVE PLUG EQUALIZER BYPASS

Type 161EB—High accuracy pilot with an outlet pressure range from 5 to 350 psig (0,34 to 24,2 bar). Pilot bleeds (exhausts) downstream through the sense (control) line.

Type 161EBM—The monitor version of the Type 161EB pilot. The pilot bleed (exhaust) is isolated from the sense (control) line. This pilot is used in monitoring systems requiring an isolated pilot bleed (exhaust).

Type 161EBH—The high-pressure version of the Type 161EB pilot with an outlet pressure range from 250 to 700 psig (17,2 to 48,3 bar).

Type 161EBHM—The high-pressure version of the Type 161EBM pilot with an outlet pressure range from 250 to 700 psig (17,2 to 48,3 bar).

Note For applications requiring extremely tight control, using a Type 161AYM, 161EBM, or 161EBHM monitor pilot will increase the accuracy of the regulator.

completely shutting off the flow of gas to the downstream system. The slam-shut has a mechanism box and a manometric device. The manometric device is a spring and diaphragm actuator. Its movement activates the detection stage of the mechanism box.The shutoff is a two stage process, the detection stage and the power stage. This separation between detection stage and power stage provides maximum precision, alleviating many false trips caused by environmental vibrations. The slam-shut device includes a bypass valve that will allow pressure to be equalized when resetting the device. Once the slam-shut device has been tripped, it must be manually reset. For more information on the Type EZR with a slam-shut device, contact the local Fisher Sales Representative or Sales Office.

Type EZR Installation

Personal injury, equipment damage, or leakage due to escaping gas or bursting of pressure-containing parts may result if this regulator is overpressured or is installed where service conditions could exceed the limits given in Specifications on page 2, or where conditions exceed any ratings of the adjacent piping or piping connections.

To avoid such injury or damage, provide pressure-relieving or pressure-limiting devices (as required by the appropriate code, regulation, or standard) to prevent service conditions from exceeding limits.

Additionally, physical damage to the regulator could break the pilot off the main valve, causing personal injury and property damage due to escaping gas. To avoid such injury and damage, install the regulator in a safe location.

When installed indoors, no remote venting is required except on the pilot spring case. This regulator can also be installed in a pit that is subject to flooding by venting the pilot spring case above the maximum possible flood level so the pilot setting can be referenced at atmospheric pressure.

1. Only personnel qualified through training and experience should install, operate, and maintain a regulator. Before installation, make sure that there is no damage to, or debris in the regulator. Also, make sure that all tubing and piping are clean and unobstructed.

Note The Type EZR optional inlet strainer is intended to prevent occasional large particles from entering the main valve. If the gas contains continuous particles, upstream filtration is recommended.

2. A Type EZR regulator may be installed in any orientation, as long as flow through the regulator matches the direction of the arrow on the main valve body. However, for easier maintenance, install the regulator with the bonnet up.

All Installations The robust design of the Type EZR allows this regulator to be installed indoors or outdoors. When installed outdoors, the Type EZR does not require protective housing. This regulator is designed to withstand the elements. The powder paint coating protects against minor impacts, abrasions, and corrosion.

When installing a Type EZR trim package in an existing E-body, make sure flow is up through the center of the cage and down through the cage slots. In some cases, correct flow path is achieved by

welding practices and remove trim before beginning to weld. Use approved piping procedures when installing the regulator.

A regulator may vent some gas to the atmosphere. In hazardous or flammable gas service, vented gas may accumulate and cause personal injury, death, or property damage due to fire or explosion.

Vent a regulator in hazardous gas service to a remote, safe location away from air intakes or any hazardous location.

Protect the vent line or stack opening against condensation or clogging.

5. A clogged pilot spring case vent may cause the regulator to function improperly. To keep this vent from being plugged (and to keep the spring case from collecting moisture, corrosive chemicals, or other foreign material) point the vent down, orient it to the lowest possible point on the spring case or otherwise protect it. Inspect the vent regularly to make sure it has not been plugged. To remotely vent a spring case, remove the vent and install obstruction-free tubing or piping into the 1/4-inch NPT vent tapping. Provide protection on a remote vent by installing a screened

8

vent cap onto the remote end of the vent pipe. The 161AY Series pilot has a vent restriction (key 55, figure 24) to enhance low flow stability. Do not remove this restriction.

To avoid freezeup because of pressure drop and moisture in the gas, use antifreeze practices such as heating or adding a de-icing agent to the supply gas.

6. As shown in figure 5, run a supply pressure line from the upstream pipeline to the restrictor inlet (use 3/8-inch outer diameter tubing or larger). Install a Type 252 pilot supply filter upstream of the restrictor, if needed, to keep the supply source from clogging the restrictor or pilot. Inspect and clean this filter regularly to make sure it has not been plugged.

7. Install a downstream pressure control line (as shown in the appropriate figure 5 drawing) to the pilot control line connection. Connect the other end of the control line at a minimum of 8 to 10 pipe diameters downstream of the regulator, in a straight run of pipe.

Do not make the control line connection in a turbulent area, such as in or directly downstream of a swage or elbow. Significant restrictions in the control line can

prevent proper pressure registration. When using a hand valve, it should be a full flow valve such as a full port ball valve. Also, with a Type 161EBM, 161EBHM or 161AYM pilot run a downstream exhaust bleed line to the downstream bleed line connection in the pilot body assembly.

8. Good piping practices ususally require swaging up to larger downstream piping to obtain reasonable downstream fluid velocity.

Wide-Open Monitor Installations 1. Follow the procedures in the All Installations section, and then continue with step 2 of this section.

2. Pilot supply for the downstream monitoring regulator must be obtained between the two regulators as shown in figure 6. With this arrangement, the downstream monitoring regulator diaphragm changes position with every load change. For sizing purposes, add the minimum differential pressure for each regulator together to establish the required pressure drop across the station. System lockup pressure is equal to the setpoint of the working regulator pilot when a

Type 161EBM or a Type 161AYM is used on an upstream regulator, otherwise lockup pressure is equal to monitor pilot lockup pressure.

Working Monitor Installations On working monitor installations, the working monitor regulator is always upstream and acts as a first-stage regulator through the working pilot during normal operation. This arrangement allows the working monitor’s performance to be observed at all times.

Then, should the second-stage regulator fail open, the working monitor regulator assumes the entire pressure reduction function of the system through the monitoring pilot.

Use the following procedure when installing a working monitor system.

1. Follow the procedures in the All Installations section, and then continue with step 2 of this section.

2. Pilot supply pressure for the downstream Type EZR regulator must be made directly upstream of the Type EZR using intermediate pressure.

3. Significant restrictions in the control line can prevent proper pressure registration. Connect the control line a minimum of 8 to 10 pipe diameters downstream of the regulator in a straight run of pipe.

Do not make the control line connection in a turbulent area, such as in or directly downstream of a swage or elbow. When used, a hand valve should be a full flow valve such as a full port ball valve.

4. Table 8 gives the spread between normal distribution pressure and the minimum pressure at which the monitor pilot can be set to take over if the working regulator fails open.

5. Table 8 shows the minimum differential pressure requirements across an individual regulator. Since this application uses a first-stage and second-stage pressure reduction, add the minimum differential pressure for each regulator together to establish the required pressure drop across the station. Do not exceed maximum pilot ratings given in table 3.

Startup and Adjustment Note Table 7 show the maximum inlet and the differential pressures for specific constructions. Use pressure gauges to monitor inlet pressure, outlet pressure, and any intermediate pressure during startup.

Startup for Both Single-Regulator and Monitoring Installations 1. Make sure all block and vent valves are closed.

2. Back out the pilot adjusting screw(s).

12

3. For easy initial startup, set the restrictor to the START position. For future startups, the restrictor can be left in the desired run position.

4. SLOWLY OPEN the valves in the following order: a. Pilot supply and control line valve(s), if used b. Inlet block valve c. Outlet block valve 5. Turn the restrictor(s) to RUN position 2 or the desired run position.

6. For a single regulator, set the pilot to the desired outlet (control) pressure according to the Pilot Adjustment procedure.

For a wide-open downstream monitor installation, adjust the upstream working pilot until intermediate pressure is higher than the desired setpoint of the monitor pilot. Adjust the downstream monitoring pilot to the desired monitoring takeover pressure. Reduce the upstream pilot to the normal outlet pressure setting.

For a wide-open upstream monitor installation, adjust the downstream working pilot to a setpoint higher than the setpoint of the monitor pilot. Adjust the upstream monitoring pilot to the desired monitor takeover pressure. Reduce the downstream pilot setting to normal outlet pressure setting.

For a working monitor installation, adjust the setpoint of the upstream monitor pilot to the desired maximum pressure. Adjust the upstream working pilot to the desired intermediate pressure setting. Adjust the downstream pilot to a pressure setting slightly above the desired takeover pressure setting. Adjust the upstream working pilot to its desired setpoint. The setpoint of the takeover pilot should be at least what is shown in table 8. The maximum may be greater. Then, establish final desired downstream pressure by adjusting the downstream working regulator pilot.

Type EZR Pilot Adjustment Remove the pilot closing cap (key 16, figure 24 or key 22, figure 25) and, on 161EB Series only, loosen the locknut (key 12, figure 24). Turn the adjusting screw (key 11, figure 24 or key 35, figure 25) into the spring case (key 2, figure 24 or key 3, figure 25) to increase the downstream pressure. Turn the adjusting screw out of the spring case to decrease the downstream pressure. When the required downstream pressure is maintained for several minutes, tighten the locknut to lock the adjusting screw in position (161EB Series only) and replace the pilot closing cap.

Figure 9. Restrictor Adjustment

Type 112 Restrictor Adjustment

Maintenance

The Type 112 restrictor controls the regulator's proportional band (droop) and speed of response. The restrictor can be used to fine tune the regulator for maximum performance by decreasing the restrictor setting for tighter control (increased opening speed, decreased closing speed); or increasing the restrictor setting for maximum stability (decreased opening speed, increased closing speed). A lower setting also provides a narrower proportional band for better accuracy. The START position has the largest flow, is most stable, and easiest for startup, however, using the START position is not necessary. The “0� setting has the smallest (minimum) flow passage; at no point of rotation will the Type 112 restrictor be completely shut off. After initial adjustment, the restrictor does not need to be adjusted for maintenance or startup.

Regulator parts are subject to normal wear and must be inspected periodically and replaced as necessary.

Due to the care Fisher takes in meeting all manufacturing requirements (heat treating, dimensional tolerances, etc.), use only replacement parts manufactured or furnished by Fisher. Also, when lubrication is required, use a good quality lubricant and sparingly coat the recommended part. The frequency of inspection and parts replacement depends upon the severity of service conditions, applicable codes and government regulations, and company inspection procedures. Table 9 lists various regulator problems and possible solutions for them.

Shutdown for Both Single-Regulator and Monitoring Installations

If pilot supply pressure is shut down first, the downstream system may be subjected to full inlet pressure.

1. If the pilot setting must be disturbed, be sure to keep some tension on the spring. This will prevent trapping inlet pressure during blow down.

2. Close the valves shown in figure 5 or 6, in the following order: (1) inlet block valve, (2) outlet block valve, and if used (3) control line valve(s).

3. Open the vent valves to depressurize the system.

14

Type EZR Main Valve Trim Parts Instructions are given for complete disassembly and assembly. Key numbers are referenced in figures 18 and 19 unless otherwise noted.

Avoid personal injury or damage to property from sudden release of pressure or uncontrolled gas or other process fluid. Before starting to disassemble, carefully release all pressures according to the shutdown procedure.

Use gauges to monitor inlet and outlet pressures while releasing these pressures.

Note The regulator may remain in the pipeline during maintenance procedures.

Type EZR Disassembly Disassembly of Type EZR: When installing a Type EZR trim package make sure flow is up through the center of the cage and down through the cage slots. In some cases, correct flow path is achieved by removing the body from the line and turning it around. If this is done, change the flow arrow to indicate the correct direction. Damage may result if flow is not in the correct direction. After assembly, check the regulator for shutoff and leakage to atmosphere.

1. Shutdown, isolate, and depressurize the main valve and pilot.

2. Remove the cap screws (key 3). Lift up and remove the bonnet (key 2) from the body (key 1).

3. Remove the diaphragm and plug assembly (key 9) and bonnet O-ring (key 28).

4. Pull out the cage (key 7), O-ring (key 8), and inlet strainer or strainer shim (key 23) (if strainer is not used).

5. Clean parts and replace if necessary.

Converting a Fisher E-Body to Type EZR: Remove all trim parts from the main valve and clean the body interior. Then follow procedure in Assembly section to convert a Fisher E-body to a Type EZR.

Assembly 1. Install the inlet strainer or shim (key 23) into the body (key 1).

2. Lightly lubricate and install the cage O-ring (key 8).

Table 9. Troubleshooting Guide PROBLEM

POSSIBLE SOLUTION

Outlet pressure suddenly rises above setpoint and approaches inlet pressure

• If travel indicator is in UP position, check restrictor and pilot supply filter for plugging • If travel indicator is in DOWN position, check main valve for debris or diaphragm damage

Outlet pressure normal at low flow but falls below setpoint at high flow

• Check main valve inlet strainer for plugging • Check inlet pressure at high flow condition • Check sizing calculations to be sure main valve body is large enough for load • Check for undersized or restricted control line (use the minimum size given in step 7 of All Installations) • Adjust restrictor to a lower setting

Outlet pressure cycles

• Adjust restrictor to a higher setting • Check control line placement. Make sure it is not located in a turbulent area.

• Make sure there is not a restriction in the control line, such as a needle valve.

Gas escapes from pilot spring case

• Replace pilot diaphragm assembly

Gas escapes from travel indicator

• Replace indicator stem O-ring, if indicator is not desired, convert to a non-travel indicator assembly

Regulator unexpectedly closes or falls below setpoint

• Check pilot for ice. Moisture in the gas can cause ice to form and build up in the pilot, blocking the flow. This most commonly occurs when ambient temperature is 30° to 40°F (-1° to 4°C). Heating the regulator or adding a de-icing agent will reduce the possibility of icing.

Outlet pressure approaches inlet pressure when no flow is desired

• Check main valve O-rings for damage or improper installation • Check cage and diaphragm surfaces for erosion or trapped debris • Check pilot valve plug and seat for seating surface damage or debris • Check pilot for ice

Regulator will not open

• Check for clogged control line • Make sure control line is installed and open • Check for damage to the main valve diaphragm • On new installations, make sure the control line and pilot supply are properly connected

Regulator will not close

• Make sure the pilot supply is properly connected • Check restrictor for clogging • Check the main valve diaphragm for damage • Check for a broken control line

High lockup pressure with slow shutdown

• Check for debris on main valve or pilot seat

High lockup pressure with fast shutdown

• Adjust restrictor to a higher setting

Setting the High Trip Point

tool stored in the box. Place the square end of the tool on the square shaft in the center of the box and slowly rotate clockwise. When movement starts on the stem, the internal bypass will open and equalize the pressure on each side of the valve plug before moving the valve plug off the seat. Continue turning the reset tool until the valve plug raises and compresses the closing spring, thus latching the second stage mechanism.

Replace the reset tool on its holder and replace the cover. Slowly open the upstream block valve.

When setting trip points on units with dual trip points (high and low trip points), set the high trip point first.

Disassembly

Slam-Shut Maintenance Refer to figures 15, 16, 17, and 31 for part location when performing the following procedures.

Setting the Trip Points Use the following procedures to set the high and low trip points of the slam-shut device.

1. Loosen the locknut and turn the spring adjusting device clockwise as far as it will go.

2. Apply the desired set pressure to the high unit diaphragm.

3. Turn the adjusting screw counterclockwise until it just touches the pin on the tripping plate.

4. Increase the pressure to test the setting.

5. Reset the slam-shut.

Avoid personal injury or damage to property from sudden release of pressure or uncontrolled gas or other process fluid. Before disassembling, carefully relieve all pressures. Use gauges to monitor inlet and outlet pressures while releasing these pressures.

1. Open the mechanism box cover.

Setting the Low Trip Point When setting trip points on units with dual trip points (high and low trip points), set the high trip point first.

1. Turn the spring adjusting device counterclockwise as far as it will go.

2. Turn the device stem counterclockwise as far as it will go.

3. Turn the spring adjusting device clockwise until the device stem moves.

4. Turn the device stem clockwise until the head just touches the pin on the tripping plate.

5. Decrease the pressure to test the trip point.

6. Reset the slam-shut.

Resetting the Trip Mechanism After the slam-shut device has tripped closed, it must be manually reset before it can be placed back in service. Before resetting, find and correct the reason for the overpressure or underpressure condition.

To reset the slam-shut device, close the upstream block valve. Open the cover of the mechanism box.

Push the red pin (found in the top center of the box) in the direction of the arrow. This action will lock in stage one. To reset the second stage, use the square reset

Trip the mechanism if it is not already released to remove as much spring tension on the stem as possible.

2. Trip the mechanisim by carefully turning the square tripping plate located by the manometric device stem clockwise.

3. Remove the screw and the red travel indicator. Pull the pin from the sliding clevis, releasing the clevis so it can be turned and detached from the stem.

4. Remove the two cap screws holding the mechanism box to the bonnet and remove the mechanism box.

5. Remove the nuts or cap screws holding the bonnet to the body.

6. The bonnet, valve plug (with equalizer bypass), closing spring, stem, and packing box will lift out of the body as a unit. Set the valve plug on a hard flat surface and press down on the bonnet to compress the closing spring allowing the stem to be unhooked from the coupling head.

7. Use a spanner wrench to unscrew the equalizer bypass from the valve plug. On the 2-inch size the equalizer bypass holds the plug disk and the seat seal O-ring to the valve plug.

1. Attach the new equalizer bypass to the coupling using a roll pin.

2. Screw the equalizer bypass into the valve plug with the plug disk and a new seat seal O-ring. Be careful not to nick or pinch the O-ring when tightening the equalizer bypass. On the 4-inch body size attach the plug disk and a new seat seal O-ring to the valve plug using six cap screws.

3. Replace the valve plug guides on the inside of the skirt of the bonnet.

4. Place a new O-ring on the packing box. Set the valve plug assembly on a hard flat surface. Set the closing spring in place on the valve plug. Place the bonnet on the spring and compress the spring by pressing down on the bonnet. Attach the stem to the coupling head of the valve plug through the bonnet.

Slowly release the bonnet allowing spring tension to seat the packing box in the bonnet, be careful to properly seat the packing box O-ring.

5. Hook the sliding clevis to the stem and insert the pin. Use the red travel indicator and screw to secure.
