SV Series

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 SV-12 valve operates on 12-VDC, has a 1/4 NPT inlet and outlet and a full 3/16 in. (5 mm) orifice. A 24-VDC (SV-24) is optional. The SV valves open against 30 psi. (207 kPa) [2.07 bar] inlet pressure. For a greater flow rate valve, we offer the special series SV valve with a 1/4 in. (6 mm) orifice which opens against maximum pressure of 15 psi (103 kPa) [1.03 bar]. This valve is recommended where greater flow is required and only static head or low transfer pump pressures are encountered.

The SV series is NOT intended for use with engines having unit injectors or distributor type injection pumps. Use only with diesel.
