FW Murphy, 55700226, SV-12-HP Diesel Fuel Shutoff Valve, 12 VDC, High Pressure
The SV series valve, which is solenoid operated, is a normally closed valve that opens when current is supplied from the battery through a magnetic switch. Temperature, level or pressure Swichgage® instruments installed on the diesel engine and pump or compressor trip the magnetic switch breaking the circuit from the battery which closes the valve and stops the engine.
The Murphy SV-HP series valves open against diesel fuel transfer pump pressure up to 60 psi (414 kPa) [4.14 bar].
The SV Series fuel shutoff valve is for use with diesel engines with externally accessible fuel injection pumps. The volume of fuel required for the engine to operate must be able to pass through the 3/16 in. (5 mm) or 1/4 in. (6 mm) orifice of the valve. You must be able to attach the fuel valve directly onto or in close proximity to the fuel injection pump in order to close off fuel flow to the pump.
