MIZER® No-Bleed Pilot Valve Application The MIZER® No-Bleed Pilot Valve is the most cost-effective solution for converting high-bleed pneumatic controls to low-bleed operation. This device effectively stops continuous bleed operation between dump cycles, thereby reducing environmentally-concerning methane emissions, while allowing previously wasted gas to be sent to the sale line. Conservatively, user can anticipate 90% savings from recaptured gas based upon estimated cycle rates of the controls. 95-98% values may be achieved in some applications.

Features • Kits Available For: • Cemco Cantilever Level Controls • FMC Invalco Flexlever Level Controls • Emerson/Fisher 2500 Level Controls • Emerson/Fisher 4100Z "Wizard" Pressure Controllers • Emerson/Fisher 4150/4160 Pressure Controllers • Cemco and FMC Invalco kits are field-installable in minutes – unit does not have to be shut down for installation. Installation of pressure controller kits, although more in-depth, are still the most painless and cost-effective solution for converting highbleed to low-bleed. • Uses existing tubing and connections – no new plumbing required. • MIZER® works in either snap acting or throttling application. • MIZER® solution allows field personnel to continue using control devices that are familiar. • Conversion from high-bleed to low-bleed may qualify user for Carbon Credits.

Bleed Gas vs. Vent Gas "Bleed" gas is defined as gas that bleeds to atmosphere between dump cycles. "Vent" gas is that gas which, after energizing the dump or control valve must be released to atmosphere, and is usually a small fraction by comparison to the bleed gas volume. It is because of the high bleed between dump cycles that the EPA discourages the use of high-bleed pneumatic devices to control liquid level and gas pressure. The MIZER® device actually stops the continuous flow of gas from these controllers, only allowing gas to flow to the con-

The

trolled device (dump valve or control valve) when necessary. Therefore, the amount of potential gas savings is dependent upon (among other things) the initial bleed rate and the frequency of operation of the controller and valve. In other words, a separator unit that fills slowly and dumps infrequently is bleeding substantial amounts of unutilized gas pressure to atmosphere most of the time. All of this gas that is vented to atmosphere between dump cycles would be saved when using a MIZER® retrofitted controller. Likewise, if the controller is very active, dumping fluid frequently, the savings would be less, as more gas is being used to activate the valve. It should be noted that neither the MIZER® nor any other lowbleed device is capable of saving gas that has been used to energize the valve. This gas will always be lost after the valve cycles and the diaphragm and connection lines vent. If the lines are not allowed to vent the valve will not return to the original (usually closed) position.

Ease of Installation The Cemco and FMC Invalco level control versions of the MIZER® pilot valve installation is a simple and painless operation. In fact, unlike installing traditional no-bleed level controllers, which require breaking the process connection, the MIZER® pilot valve is installed by simply removing the operating gas pressure from the controller, installing the MIZER®, blowing out the supply line to keep it clean, reattaching the supply line and adjusting. Different controllers require different kits–some containing more parts than others. Retrofit kits for pressure controllers such as the Emerson/Fisher 4150 or 4160 are more complex and therefore the procedure is also more complex, possibly requiring shut down. But, no welding of new fittings, no new tubing, no new cabinet refits are required. The MIZER® installs in minutes – not hours or days as is the case with installation of any complete new controller. Last, but not least, the operator continues using the controller they already know and trust – no need to learn the operating quirks of a completely new control.

Installation and Calibration Instructions for Model 1110 WARNING

Retrofit Kit

for Cemco Cantilever Level Control Nozzle Seat

User must isolate the control from signal pressure prior to disassembly and installation of this product. Failure to do so may result in free flow of gas during installation, property damage and/or personal injury. Always employ upstream and downstream pressure gauges to monitor startup pressures.

Application The Model 1110 Retrofit Kit is designed to convert an existing continous-bleed Cemco Model 6900 Level Control to a non-continousbleed configuration. This reconfiguration results in significant gas savings, as well as providing a much cleaner and safer environment. The MIZER® Pilot Valve will operate in both Snap-Acting and Throttling applications. User must realize that liquid level control performance is a function of the efficiency of both the control AND the valve, as some valves flow more efficiently than others. This device can be installed without shutting down or draining the unit, thereby eliminating concerns about spills or lost production. However, since the control will be inactive during the retrofit, and to avert any possibility of overfill during this procedure, it is recommended that installation take place while the vessel is in a low liquid condition.

Installation and Calibration Shut off supply pressure and process pressure to the controller. Remove the controller adjustment screw and blow out the supply line to remove any debris. Lubricate the MIZER® O-rings with a multi-purpose grease and insert the MIZER® Pilot Valve, screwing it clockwise until the tip reaches the nozzle seat. ®

Turn on supply pressure to the controller. Adjust the MIZER® Pilot Valve in and out until the desired pressure is achieved

How the MIZER Pilot Valve Operates

NOTE: Clockwise adjustment will LOWER the fluid level. Counter-clockwise adjustment will RAISE the fluid level. Once set, lock the MIZER® Pilot Valve in place by tightening the supplied jam nut
