Woodward 8915-1025 Rotating Sleeve Type Gas Metering Valve

Product Description

Woodward 8915-1025 is an integrated assembly of 3103 (R3103) rotary sleeve gas metering valve and EM35MR electric actuator. It serves as the final regulating device in the gas turbine fuel control loop. Adopting all-electric design without hydraulic supply, it is equipped with resolver position feedback. It receives setpoint signals from master controllers to precisely modulate gas fuel flow. It features excellent linearity, fast response, compatibility with DLE low-emission combustion systems, high vibration resistance and wide temperature tolerance, designed for continuous-duty gas turbines in power plantsManualsLib.
