FEATURES & FUNCTIONALITY
Woodward’s Gas Shutoff Valve (GSOV) platform provides high speed fuel shutoff for emergency and normal shutdown of industrial gas turbines.
 
The valve operates at pressures up to 900 psia (6.2 Mpa) and, with its all stainless steel construction, assures availability of the valve under all operating conditions. The valve design allows minimum pressure drop by utilizing a straight through flow. This also keeps all critical moving parts and seals out of the flow stream.
 
The Woodward GSOV25 HT 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 GSOV25 HT is suitable for use on industrial turbines in the 10 to 50 MW power output range with single or multiple combustion fuel manifold systems.
 
Features:
  • Rated at <10 psi (69 kPa) pressure drop at flow of 25 000 lb/h (11 340 kg/h)
  • Fuel temperature range –4 to +350 °F (–20 to +177 °C)
  • Closes in <0.100 seconds at 900 psig (6200 kPa)
  • Better than Class VI shutoff
  • 100 to 900 psig (690 to 6200 kPa) operating pressure
  • 500 psig (3448 kPa) reverse pressure capable
  • Certified for North American Hazardous Locations
  • Certified for use in explosive atmospheres within the Russian Federation
  • Designed for natural gas, propane, ethane, or methane
  • Operates from line pressure with no external connections required or with external pilot pressure
