Applications

The Woodward GSOV50 fuel isolation valve is designed to provide extremely fast

shutoff of gaseous fuel flow to an industrial gas turbine engine. Gas flow is stopped

when the valve is closed, with zero leakage from inlet to outlet. The HT version can

withstand higher fuel temperatures and higher back pressures than the standard version.

It is suitable for operation with gas temperatures between –4 and +350 °F (–20 and +177 °C).

The valve can achieve ANSI Class VI shut-off capability in the reverse flow direction with

a pressure differential of 500 psi (3448 kPa).

The normally-closed valve may be used for emergency and normal shutdown

operations. The special seal design in the main piston valve allows long life and

prevents leakage. Stainless steel construction ensures valve availability despite

corrosive service conditions.

This product is suitable for use on industrial turbines in the 10 to 50 MW power

output range with single or multiple combustion fuel manifold systems.
