Parker DT-620-MFMF-5 Hydraulic Check Valve 15 Gpm

Product Description

The PARKER DT-620-MFMF-5 is a hydraulic control check valve designed to allow flow in one direction while blocking reverse flow in a hydraulic circuit. Built with a steel body and metal seals, it handles flow rates up to 15 GPM and working pressures up to 3,500 psi. The 7/8-14 Male JIC thread standard ensures a secure, leak-resistant connection at the inlet. At 2.02 inches in overall length and a compact 1.06-inch profile in both width and height, this valve fits in tight manifold and plumbing configurations. It is installed by hydraulic system technicians and maintenance mechanics working on mobile or industrial hydraulic equipment.

This check valve is suited for use in hydraulic power units, mobile equipment hydraulic circuits, and industrial machinery where controlled unidirectional flow is required. The 7/8-14 Male JIC inlet makes it compatible with standard JIC hydraulic fittings commonly found in construction, agricultural, and manufacturing equipment. Its all-steel construction with metal seals makes it appropriate for high-pressure service in demanding duty cycles where fluid compatibility with elastomeric seals is a concern.

Key Features

• Maximum flow rate of 15 GPM for moderate- to high-flow hydraulic circuits
• Rated to 3,500 psi maximum working pressure for high-pressure hydraulic systems
• 7/8-14 Male JIC inlet thread for secure, standard hydraulic connections
• Steel body construction for durability in demanding hydraulic environments
• Metal seal material suitable for high-pressure and fluid-compatibility requirements
• Compact envelope at 2.02 inches length and 1.06 inches width and height for tight installations

Compatibility

Designed as an OEM-style replacement or new-installation check valve for hydraulic systems using 7/8-14 Male JIC fittings operating within 15 GPM and 3,500 psi ratings.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Depressurize and de-energize the hydraulic system completely before removing or installing any valve components. Verify thread engagement and torque fittings to the system manufacturer's specifications using appropriate hydraulic wrenches. Ensure flow direction is oriented correctly before returning the system to service, as reversing inlet and outlet will prevent proper check function.
