Pull/Push DC Solenoids for
Diesel Engines
Description
Murphy push/pull DC Solenoids
provide single unit versatility for engine
applications, such as shutdown.
A choice of two models and two
voltages is available. All models come
complete with return spring and rubber
seal boot. See the next page for
specifications and options.
Basic Models
Models RP2307B and RP2308B give a
full one inch (25 mm) stroke at 11
pounds (49 N) and hold up to 23 pounds
(102 N) at full voltage, continuous duty.
They will operate at any stroke less than
maximum; refer to the chart shown on
page 2.
Models RP2309B and RP2310B can
pull 14 pounds (62 N) with a one-and-a-
half inch (38 mm) stroke. They hold up
to 34 pounds (151 N) at full voltage,
continuous duty. See the chart on page 2
for holding force at any stroke less than
maximum.
SD85 Solenoid Drive
Time Delay
Using the SD85 ensures the energize
coil is only powered for 1-2 seconds
with each operation. If the plunger does
not seat in that time, it is highly
unlikely it will seat. The hold coil is
energized as long as the signal to the
SD85 is active. This insures long life of
the RP solenoid.

A limited warranty on materials and workmanship
is given with this FW Murphy product. A copy of
