GSOV25 Gas Shutoff Valve

Applications

The Woodward GSOV25 gas shutoff valve is designed to provide extremely fast shutoff of any gaseous flow for industrial gas turbines. Gas flow is stopped when the valve is closed, with zero leakage from inlet to outlet.

The normally closed valve may  be used for emergency and  normal shutdown  operation. The  special seal design  in the main piston  valve allows long life and prevents leakage. Stainless steel construction assures availability of the valve in spite of corrosive service conditions.

Description

The GSOV25 gas shutoff valve provides shutdown on a gas turbine by rapidly halting the flow of gaseous fuel. The supply pressure is used to move a springloaded piston in the valve. When the valve is energized, gas pressure drives the  spring-loaded piston open, admitting fuel to the turbine. When the current signal to the electrical solenoid is interrupted, the spring loaded second-stage piston changes states to vent off primary control pressure. The main spring then forces the primary piston to the seal, stopping flow.
