Parker DT-750-MFMF-65 Hydraulic Check Valve 30 Gpm

Product Description

The PARKER DT-750-MFMF-65 is a hydraulic control check valve designed to permit flow in one direction while preventing reverse flow in hydraulic circuits. Built with a steel body and metal seals, it handles flow rates up to 30 GPM and working pressures up to 3,500 psi. The 1-1/16-12 Male JIC thread inlet provides a secure, leak-resistant connection compatible with standard JIC hydraulic fittings. At 2.22 inches in overall length, it fits into compact manifold and inline installations. This valve is installed by hydraulic system technicians and mechanical contractors working on industrial, mobile, and heavy-equipment hydraulic systems.

The DT-750-MFMF-65 is suited for use in high-pressure hydraulic circuits where directional flow control is required. Typical applications include mobile equipment, industrial machinery, and fluid power systems that demand reliable check function under sustained pressure. The Male JIC thread configuration makes it straightforward to integrate into existing JIC-plumbed hydraulic lines without adapters. Its compact envelope — 1.25 inches wide and 1.25 inches tall — allows installation in space-constrained locations on equipment frames and hydraulic power units.

Compatibility

Designed as an OEM-style replacement or drop-in component for hydraulic circuits using 1-1/16-12 Male JIC threaded connections rated to 30 GPM and 3,500 psi.

Installation Notes

Installation should be performed by a qualified hydraulic technician or mechanical contractor familiar with fluid power systems. Depressurize and bleed the hydraulic circuit completely before removing or installing any valve components. Verify that system pressure and flow ratings do not exceed the valve specifications before putting the system back into service. Follow applicable fluid power safety standards and equipment manufacturer guidelines when integrating this valve into a hydraulic circuit.
