Murphy offers two types of diesel fuel line
valves: check valves and pressure relief
valves. 
The  CKV series  check valves are in-line,
one-way valves that prevent fuel from being
siphoned back into an injector or injection
pump which could delay a shutdown.  
There are two types of check valves:
CKV2336 and CKV1WPS. The CKV2336
has a 1/4 NPT threaded male connection on
each end for connecting to fuel line fittings
or hoses. The CKV1WPS check valve is typi-
cally mounted in the fuel bypass line of the
last fuel injector. The CKV1WPS features a
hollow bolt connection and a barbed, 1/8
NPT connection for flex hose or fitting.
The PRV series pressure relief valves,
relieve overpressure in a fuel system usually
caused by closing of a solenoid fuel valve.
The PRV50 and PRV70 have a 1/4 NPT
threaded connection on each end for con-
necting to fuel line fittings or hoses.
