CKV / PRV SERIES

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 typically 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 connecting to fuel line fittings or hoses.
