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

Product Description

The PARKER DT-370-MFMF-65 is a hydraulic control check valve designed to allow one-directional fluid flow while preventing backflow in hydraulic systems. Built from steel with metal seals, this compact valve handles a maximum working pressure of 5000 psi and a maximum flow rate of 8 GPM. Its 9/16-18 Male JIC thread configuration suits a wide range of mobile and industrial hydraulic circuits. The overall length is 1.56 inches, with a height and width of 0.75 inches each, making it a space-efficient solution for inline installation. Hydraulic technicians and fluid power specialists install this valve where directional flow control and backflow prevention are required.

This check valve fits inline hydraulic plumbing on mobile equipment, industrial machinery, and fluid power systems where Male JIC fittings are standard. It is well suited for applications demanding reliable flow control at high operating pressures, including agricultural equipment, construction machinery, and manufacturing hydraulic circuits. Its all-steel construction and metal seals make it appropriate for use with petroleum-based and compatible synthetic hydraulic fluids.

Key Features

Compatibility

Designed as an OEM-style replacement or new-installation check valve for hydraulic systems using 9/16-18 Male JIC threaded fittings and operating within a 5000 psi maximum working pressure range.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and de-energize the hydraulic system completely before removing any fittings or installing this valve. Verify thread type and size compatibility before torquing to avoid galling or cross-threading on JIC connections. Follow applicable fluid power industry standards and equipment manufacturer guidelines during installation and system restart.
