This SD85 is used when the solenoid is duty cycled
for short time periods such as 2-position throttle op-
eration. It also provides enhanced operational control
for normal on-off applications. Activates both coils of
the solenoid for a short time then de-energizes the
Energize-coil. The Hold-in coil remains energized.

RP Series push/pull DC Solenoids provide single unit versatility for engine applications, such as shutdown.
Unlike most existing solenoids, this line features three-wire circuitry, which reduces the chance for burned
up coils due to incomplete seating of the plunger. If the plunger does not “seat” due to improper linkage
adjustment, the solenoid coil will release the plunger. This allows it to return to the “tripped” position, thus
overcoming coil burnout. A choice of two models and two voltages is available. All models come with return
spring and rubber seal boot.

Solenoid Operated Fuel Shutoff Valve |
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
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. The standard
SV-12 valve operates on 12V DC, has a ¼” NPT
inlet and outlet, and a full 3/16” (5 mm) orice. Other
voltages are optional. The standard SV valves open
against 30 psi. (207 kPa) inlet pressure.
The SV Series fuel shutoff valve is intended for use
with diesel engines having externally accessible
fuel injection pumps. The volume of fuel required for
the engine to operate must be able to pass through
the 3/16” (5 mm) orice of the valve. You must be
able to attach the fuel valve directly onto or in close
proximity to the fuel injection pump in order to close
off fuel ow to the pump. The SV series IS NOT
intended for use with engines having “unit” injectors.
Use only with diesel.

CRV and PRV Series Diesel Fuel Check Valves |
CKV Series is an in-line, one-way valve for the pre-
vention of fuel siphoning from the diesel return line by
an injection pump in engine shutdown systems using
a Murphy SV valve. The CKV is necessary to ensure
a rapid shut down of the engine by fuel starvation of
the injection system. ¼” NPT.

PRV50 is an in-line, one-way valve for the prevention
of over pressure damage to fuel lters and their
housings. This pressure relief valve operates in
conjunction with a Murphy SV series shutdown valve.
After the SV closes, a rapid high pressure build-up
caused by the fuel pump can occur. The PRV,
mounted in a fuel return line after the lter, will open
to relieve pressure buildup. ¼” NPT.
