The CKV-2336 Diesel Fuel Check Valve is an in-line, one-way valve that prevents fuel from being siphoned back into an injector or injection pump which could delay a shutdown. In engine shutdown systems using a Murphy SV valve, the CKV is necessary to ensure a rapid shutdown of the engine by fuel starvation of the injection system.

The CKV-2336 Diesel Fuel Check Valve has 1/4" (6 mm) NPT threaded male connections on each end for connecting to fuel line fittings or hoses. The valve has a solid brass body, poppet seal and a stainless steel spring. Opening pressure is 1.0 psi (7 kPa). Fully opened pressure is rated at 4 psi (27 kPa). Static pressure is 150 psi (1.03 MPa). The valve measures 1-5/8" in length.
