Description
The SV-series valve is a normally closed valve that
opens when current is supplied from the battery
through a magnetic switch. Temperature, level, or

instruments installed on
the engine and pump or compressor, trip the mag-
netic switch, breaking the circuit from the battery
which closes the valve and stops the engine.
The SV-12 valve operates on 12VDC, has a 1/4 NPT
inlet and outlet, and a full 3/16 in. (5 mm) orifice.
24 VDC (SV-24) is optional The SV valves open
against 30 psi. (207 kPa) [2.07 bar] inlet pressure.
Greater Flow Rate Valve
Special series SV valve is available 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.
High Pressure Valves
SV-HP series valves open against diesel fuel
transfer pump pressure up to 60 psi (414 kPa)
[4.14 bar]. Models are available for 12 or 24 volt
DC systems. The orifice is 1/4 in. (6 mm), using
the same inlet/outlet and options as standard SV.
