The Murphy Diesel-Fuel Shutoff Valve SV-12-4 is a solenoid operated type that operates on 12 VDC. The SV valve opens against 30 psi (207 kPa) [2.07 bar] inlet pressure, it has a 1/4 inch (6 mm) diameter orifice and 1/4 NPT inlet and outlet. This model 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 engine and pump or compressor trip the magnetic switch, breaking the circuit from the battery, which closes the valve and stops the engine.
