Parker DT-370-MOMF-65 Hydraulic Check Valve 8 Gpm

Product Description

The PARKER DT-370-MOMF-65 is a hydraulic control check valve designed to allow flow in one direction while preventing backflow in hydraulic circuits. Built from steel with metal seals, it handles up to 8 GPM flow and a maximum working pressure of 5,000 psi. The valve uses a Male ORB x Male JIC thread configuration with a 9/16-18 inlet, making it a compact inline solution for high-pressure hydraulic lines. Its small footprint — 1.47 inches in overall length and 0.75 inches in both width and height — suits tight plumbing spaces on mobile and industrial equipment. Hydraulic technicians and fluid power specialists are the primary installers.

This check valve is suited for mobile hydraulic systems, industrial machinery, and equipment where backflow prevention is required in high-pressure circuits operating up to 5,000 psi. The Male ORB x Male JIC thread configuration makes it compatible with standard hydraulic fittings common in agricultural, construction, and industrial applications. Its compact steel body fits inline between hydraulic lines without requiring custom adapters in most standard installations.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Fully depressurize and de-energize the hydraulic system before removing or installing any valve components. Verify thread type and torque fittings per the equipment manufacturer's specifications using calibrated hydraulic fitting tools. Inspect all sealing surfaces for contamination before assembly to prevent leakage under pressure.
