    8654 Series Quick Shutoff Valve Double Block & Bleed

The Young & Franklin 8654 Series Quick Shut-Off Valve is a high speed, solenoid operated shutoff valve and is designed for use on combustion or gas turbine engines. There is a single main stage inlet port, an outlet port, and pilot stage plus a vent port. The valve can be used to rapidly shut off flow and isolate the source from the turbine engine, and bi‐directional sealing in closed position prevents backflow from the combustion chamber. The valve can be used with air and natural gas and are NACE compliant.
