3103 with EM35MR Electric Powered Actuator

    The 3103 gas valve is a rotary sleeve-and-shoe type-throttling valve. The metering port area is determined by input shaft position from the actuator. Valve position feedback to the actuator driver is accomplished using a high accuracy resolver. The EM35MR actuator is designed for use with the DVP (Digital Valve Positioner). The motor is a brushless dc motor with a motor clutch and gear-head assembly. The motor uses Samarium Cobalt permanent magnets bonded and sleeved to the rotor element. Rotor position sensing is performed using a resolver.

    The 3103 gas valve is a stainless steel valve capable of metering gas flow between 23 kg/h and 18 144 kg/h (50 lb/h and 40 000 lb/h). Design of the valve is to be corrosion resistant and self-cleaning, allowing it to operate in sour gas environments (high sulfur content gas) that can cause problems for other valves. When used in conjunction with an EM35MR actuator, the 3103 valve delivers the demanding accuracy needed for DLE applications.

    The EM35MR actuator is all electric, reducing hydraulic contamination and maintenance problems. Since there is no HPU to maintain or replace cost reductions are realized. In addition, the EM35MR actuator is designed for long life, although it may be replaced in the field if necessary.
