The 3103 gas valve is a rotary sleeve-and-shoe type-throttling valve.

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).

Features and Benefits

• 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

• The EM35MR actuator is all electric, reducing hydraulic contamination and maintenance problems

• The DVP uses the latest in Woodward control architecture, robust controller to provide high-speed

precise valve control
