Description

The GSOV50 fuel isolation valve provides shutdown on a gas turbine by rapidly

halting the flow of gaseous fuel. The supply pressure is used to move a spring

loaded 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 all flow.
