Parker CV-370-MFMF-65 Check Valve 13 Gpm 3000 Psi

Product Description

The PARKER CV-370-MFMF-65 is a hydraulic control check valve designed to allow flow in one direction while preventing reverse flow in hydraulic circuits. Built with a steel body and nitrile seals, it handles up to 13 GPM and a maximum working pressure of 3,000 psi. The inlet and outlet are both 9/16-18 Male JIC threaded connections, making integration into standard hydraulic lines straightforward. At 1.75 inches in overall length and 0.81 inches in both width and height, this is a compact inline component suited for space-constrained hydraulic assemblies. Licensed hydraulic technicians and fluid power specialists are the primary installers.

This check valve fits into hydraulic systems where preventing backflow is critical to circuit function and component protection. Typical applications include mobile hydraulic equipment, industrial machinery, and fluid power control circuits that use Male JIC fittings. The 9/16-18 thread standard is common across a wide range of hydraulic plumbing configurations, making this valve a practical fit for new builds and service replacements alike. It is sold individually with a minimum order quantity of one.

Installation Notes

Installation should be performed by a qualified fluid power technician or hydraulic systems specialist. Depressurize and de-energize the hydraulic circuit fully before removing any existing valve or fitting. Verify thread engagement and use appropriate thread sealant or fitting practices per system requirements. Confirm flow direction markings on the valve body align with intended circuit flow before final assembly.
