Fuel Shutoff Valves

Diesel Fuel Shutoff Valves

Diesel engine fuel shutoff valves are designed for applications where fuel shut down is required as a part of automatic engine shutdown systems.  The hydromechanical engine fuel shutoff valves are designed for use as failsafe valves in oil pressure based hydromechanical systems.  The air intake depression engine fuel shutoff valve is designed to operate in combination with diesel engine air intake shutoff valves.
