Description

fully retracts the piston rod towards the top of the cylinder upon loss of loading pressure.

The Type 1066 is a direct-acting pneumatically operated actuator. The Type 1066SR is a spring- return pneumatically operated actuator with a positioner (see figure 1). Both actuators are used for throttling or onoff applications with splined shaft valves. These actuators can be used on edisc Type 8532 and 8560 valves, Design CV500, V500, Vee-Ballr Design V150, V200, V300, and Type 9500 valves. The Type 1066SR

The actuator is field-reversible between PDTO (pushdown-to-close) and PDTO (push-down-to-open) action depending on mounting position (see figure 2). Refer to the Actuator Mounting section to change valve/actuator action or its position. The G mounting adaptation is for Type 9500 rotary butterfly valves, and the F mounting adaptation is for most other rotary high performance valves.

1. Total volume to stroke piston down is equal to displacement volume plus clearance volume above piston.

Specifications Specifications for the Type 1066 or 1066SR rotary actuator are shown in table 1. Specifications for the actuator as it originally came from the factory are stamped on a nameplate attached to the actuator.

Installation When an actuator and valve are shipped together, the actuator is normally mounted on the valve. Follow the valve instruction manual when installing the control valve in the pipeline. If it is necessary to mount the actuator on the valve, or if it is necessary to change actuator mounting positions, perform the Actuator Mounting procedure. Because of the valve travel adjustments required, it is recommended that the valve be removed from the pipeline.

WARNING This WARNING applies specifically to Type 1066 actuators, and to specially modified Type 1066SR actuators that apply pressure to the bottom of the piston (key 3, figures 4 and 5). To avoid personal injury from the bearing (key 4, figure 3) being forced out of the actuator with sufficient energy to cause personal injury or property damage, carefully follow the instructions given below. Do not apply loading pressure to a partially assembled actuator. Do not remove the mounting yoke (key 25, figure 3) or the travel indicator scale (key 21, figure 3) from the actuator assembly when loading pressure is applied to the bottom of the piston. The bearing (key 4) could be forced out of the actuator assembly. Depending on the mounting position, either the mounting yoke ( key 25) or the travel indicator scale (key 21) retains the bearing (key 4) when cylinder pressure is applied below the piston. For mounting positions A and D, the mounting yoke (key 25) holds the bearing in place when pressure is applied below the piston. In the case of mounting positions B and C, the indicator scale (key 21) holds the bearing in place when pressure is applied below the piston. Refer to figure 2 for available mounting positions. When mounting on a Vee-Ball Design V150, V200 or V300 valve, check the valve manual to determine if it is Series B. Make sure the mounting bracket is located on the correct side of the actuator to match your application.

WARNING To avoid personal injury or property damage caused by bursting of pressure retaining parts, be certain the cylinder pressure does not exceed the limits shown in table 1 or on the nameplate. Use pressure limiting or pressure relieving devices to prevent the cylinder pressure from exceeding this limit.

Actuator Mounting Use the following steps to connect a valve and actuator that have been ordered separately, or separated for maintenance. This procedure can also be performed to change actuator mounting positions. Key numbers are shown in figure 6 or 7 unless otherwise noted.

Disassembly

WARNING Avoid personal injury from sudden release of process pressure or uncontrolled movements of parts. Before performing any maintenance operations: D Disconnect any actuator operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the actuator spring compression cannot suddenly open or close the valve. Vent actuator loading pressure.

D Use process bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure on both sides of the valve. Drain the process media from both sides of the valve. Use caution when handling hazardous process media. D Use lockout procedures to ensure that the above measures stay in effect while you are working on the equipment. Always wear protective gloves, clothing, and eyewear when performing any maintenance operations to avoid personal injury. The valve packing are may contain process fluids that are pressurized, even when the valve has been removed from the pipeline. Process fluids may spray out under pressure when removing the packing hardware or packing rings.

1. Isolate the control valve from the line pressure, release pressure from both sides of the valve body, and drain the process media from both sides of the valve. Also, shut off all pressure lines, and release all pressure to the actuator. Use lock-out procedures to be sure that the above measures stay in effect while you work on the equipment. 2. Refer to figure 2 for available mounting positions. The actuator is normally positioned vertically on a valve that is installed with the shaft horizontal in the pipeline as shown in figure 2. 3. Remove the machine screws (key 24), the travel indicator (key 22), and the spacer (key 26) from the actuator.

CAUTION When removing the actuator from the valve, do not use a hammer or similar tool to drive the hub and bearing assembly off the valve shaft. This could damage the valve internal parts.


Types 1066 & 1066SR If necessary, use a wheel puller to remove the hub and bearing assembly or actuator from the valve shaft. It is ok to tap the wheel puller screw lightly to loosen the actuator, but hitting the screw with excessive force could damage internal valve parts. 4. Remove the actuator assembly from the valve shaft.

Assembly 1. Position the actuator according to the appropriate mounting position you have selected. 2. If the mounting position and style desired requires moving the mounting yoke (key 25) and travel indicator scale (key 21) to opposite sides of the actuator, remove the cap screws (key 20) from both sides of the actuator. Then, remove the mounting yoke and travel indicator scale and position them on the appropriate sides of the actuator. 3. Secure the mounting yoke and travel indicator scale to the actuator with the cap screws (key 20). Tighten the cap screws to 25 Nm (18 lbfft) for size 20 and 27 actuators and to 102 Nm (75 lbf ft) for size 75 actuators. 4. The index mark on the valve shaft must be aligned with one of the four index holes on the end of the actuator hub (key 6).

8. Perform the Adjustment procedures before applying actuator loading pressure.

Loading Pressure Connection The actuator should have either a loading solenoid, a switching valve, or a positioner connected to the 1/4-inch NPT pressure connections located at the top of the actuator cylinder. Refer to figures 5 and 6. 1. Connect either 6.4 mm (1/4-inch) or 9.5 mm (3/8-inch) tubing between the actuator pressure connection and a controlling instrument. Keep the length of tubing as short as possible to avoid transmission lag in the control signal. For further information if using a positioner, please refer to the appropriate manual. For Type 1066 actuators with a handwheel or wrench override, provide an actuator bypass valve and tubing between the two loading pressure connections (not shown). Pressure trapped in the cylinder can make it difficult to change the piston position if pressure connections are blocked because of an external device.

CAUTION The actuator travel stop must be adjusted so the valve does not absorb the output of the actuator. Failure to limit the actuator travel as described in this manual or in the valve manual can result in damage to the valve, shaft(s), or other valve components.

Consult the appropriate valve instruction manual for lever/shaft index mark or hole to position the shaft correctly. Be sure valve/actuator action is matched. Some valve applications require PDTO (push- down-to-open) fail action, while others require PDTC (push-down-toclose) fail action. Most valves or other applications require the actuator to limit travel to prevent damage. Mount the actuator on the valve so that the hub slides onto the shaft without damaging the hub.

2. Check the control valve assembly for correct action after it is completely installed and connected. For successful operation, the piston rod (key 5) and valve shaft should move freely in response to loading pressure changes on the piston (key 3).

5. Secure the mounting yoke (key 25) to the valve body as follows:

Adjustment

D If using the F Mounting Style, secure the mounting yoke to the valve body with the valve body cap screws. Tighten the cap screws to the torque given in the valve instruction manual. D If using the G Mounting Style, secure the mounting yoke to the valve body with the cap screws and washers (keys 36 and 38, not shown). Tighten the cap screws. 6. Install the spacer (key 26). 7. Note the actuator position, the valve disk or ball position, and the direction of rotation. Position the travel indicator (key 22) accordingly and fasten it with the machine screws (key 24).

The actuator is factory set for a full 90 degrees of valve shaft rotation unless otherwise specified by the customer. Control actuator/valve assemblies are factory set as specified by customer order. If the actuator is removed from the valve or if valve travel appears to be incorrect, re-adjust as necessary. (Note: Refer to the CAUTION provided in the Loading Pressure Connection section above. Over-travel of the valve can cause damage to the valve components.) 1. Isolate the control valve from the line pressure, release pressure from both sides of the valve, and drain the process media from both sides of the valve. Shut off all pressure lines to the actuator, and release the pressure. Use lock-out procedures to be sure that the above measures stay in effect while you work on the

equipment. Refer to the WARNING at the beginning of the Disassembly steps for more information. 2. Adjust the actuator stops to match the valve rotation. Adjustments must be made after installing the actuator on the valve. 3. Loosen the hex nuts (key 37 or 13, Type 1066 or 1066SR) and turn the set screws (key 12). Top and bottom piston position limits are set with the upper and lower set screws respectively. If rotation of either set screw seems difficult, apply Lubriplate MAG-1 lubricant or equivalent (key 35) to the threads of each set screw as shown in figures 5 and 6.

Principle of Operation Type 1066 Actuators: Piston movement is accomplished by loading air pressure on one side of the piston (key 3, figure 4), while unloading air pressure from the other side. The piston moves a lever (key 10) to open or close the valve. To operate the actuator, a positioner, a loading solenoid, a four-way switching valve, or two three-way valves are required, for actuators equipped with the wrench override option, or with a Type 1078 handwheel. These devices can be used to manually position the control valve without supply or instrument air pressure. Be sure to open the cylinder bypass valve to equalize pressure before manually operating the valve/actuator assembly. Type 1066SR Actuators: Piston movement is accomplished by loading air pressure on top of the piston (key 3, figure 5) to move the piston down. This action compresses the spring. If loading pressure is de-

6

creased or removed, spring compression moves the piston to the top of the cylinder. The piston moves a lever (key 10) to open or close the valve. To operate the actuator, use a positioner, a loading solenoid, or a switching valve.

Maintenance Actuator parts are subject to normal wear and must be inspected and replaced as necessary. The frequency of inspection and replacement depends upon the severity of service conditions. Because of the care Fisher Controls takes in meeting all manufacturing requirements (heat treating, dimensional tolerances, etc.), use only replacement parts manufactured or furnished by Fisher Controls. Instructions are given in this section for replacing the cylinder O-ring, the cylinder gasket, the lever/bearing assembly, and other parts. Key numbers are shown in figures 6 and 7 unless otherwise noted.

WARNING Avoid personal injury from sudden release of process pressure or uncontrolled movements of parts. Before performing any maintenance operations: D Disconnect any actuator operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the actuator spring compression cannot suddenly open or close the valve. Vent actuator loading pressure.


Types 1066 & 1066SR D Use process bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure on both sides of the valve. Drain the process media from both sides of the valve. Use caution when handling hazardous process media. D Use lockout procedures to ensure that the above measures stay in effect while you are working on the equipment. Always wear protective gloves, clothing, and eyewear when performing any maintenance operations to avoid personal injury. The valve packing are may contain process fluids that are pressurized, even when the valve has been removed from the pipeline. Process fluids may spray out under pressure when removing the packing hardware or packing rings.

WARNING This WARNING applies specifically to Type 1066 actuators, and to specially modified Type 1066SR actuators that apply pressure to the bottom of the piston (key 3, figures 5 and 6). To avoid personal injury from the bearing (key 4, figure 3) being forced out of the actuator with sufficient energy to cause personal injury or property damage, carefully follow the instructions given below. Do not apply loading pressure to a partially assembled actuator. Do not remove the mounting yoke (key 25, figure 3) or the travel indicator scale (key 21, figure 3) from the actuator assembly when loading pressure is applied to the bottom of the piston. The bearing (key 4) could be forced out of the actuator assembly. Depending on the mounting position, either the mounting yoke ( key 25) or the travel indicator scale (key 21) retains the bearing (key 4) when cylinder pressure is applied below the piston. For mounting positions A and D, the mounting yoke (key 25) retains the bearing in place when pressure is applied below the piston. In the case of mounting positions B and C, the indicator scale (key 21) retains the bearing in place when pressure is applied below the piston.

Disassembly 1. Isolate the control valve from the line pressure, release pressure from both sides of the valve, and drain the process media from both sides of the valve. Shut off all pressure lines to the actuator, and release the pressure. Use lockout procedures to be sure that the above measures stay in effect while you work on the equipment.

WARNING When removing the hex nuts (key 31), be sure spring pre-compression is not acting on the cylinder cover (key 2). The spring compression could result in personal injury by causing the cylinder cover to suddenly release from the actuator as the nuts are removed. 2. Remove the hex nuts (key 31), the flat washer (key 15), the cylinder cover (key 2), and the cylinder (key 8). 3. Inspect the O-ring (key 17) and the gasket (key 33) for nicks or flat spots that might cause leakage. Obtain all replacement parts necessary for re-assembly. 4. If replacing the O-ring and gasket (key 17 or 33 Type) is the only maintenance necessary, skip the remaining steps. Refer to the following Assembly procedure.

WARNING For 1066SR Only: Avoid personal injury from the sudden release of spring precompression by carefully following step 5 below. 5. Type 1066SR Only: Loosen the cap screw (key 19) a few turns, but do not fully disengage the cap screw threads from the piston rod at this time. Be sure the piston (key 3) disengages from the end of the piston rod (key 5) as the cap screw is being unscrewed. If the cap screw is completely removed without removing spring pre-compression the piston can be suddenly forced off the piston rod possibly causing personal injury or damage. If you are unsure of the amount of the spring pre-compression resting on the cap screw, provide an alternate method of containing spring compression before completely removing the cap screw (key 19, figure 8). 6. Remove the cap screw (key 19). Remove the sealing washer (key 11), piston (key 3), and spring (key 7, for Type 1066SR). For size 20 actuators, a flat washer (key 23) will also be removed with these parts. 7. Remove the machine screws (key 24), the travel indicator (key 22), and the spacer (key 26).
