The SV-12-HP is a High Pressure Solenoid Operated Diesel Fuel Shutoff Valve for a 12 volt system. This model has a 1/4 NPT inlet and outlet, and a 1/4 inch (6 mm) orifice. The SV-HP valves open against diesel fuel transfer pump pressure up to 60 psi (414 kPa) [4.14 bar]. This valve is recommended where greater pump pressure is required.
The SV-12-HP valve 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.
