The SV-24-4 is a Solenoid Operated Diesel Fuel Shutoff Valve for a 24 volt system. This model has a 1/4 NPT inlet and outlet, and an optional 1/4 inch (6 mm) orifice. The SV-4 valves open against 15 psi (103 kPa) [1.03 bar] inlet pressure. This valve is recommended where greater flow is required, and only static head or low transfer pump pressures are encountered.
The SV-24-4 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.
