Parker DC-750-FOFO-65 Hydraulic Check Valve 55 Gpm

Product Description

The PARKER DC-750-FOFO-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 a maximum working pressure of 3000 psi and a maximum flow rate of 55 GPM. The valve uses a 1-1/16-12 Female ORB (O-ring Boss) thread on the inlet, providing a reliable, leak-resistant connection common in industrial and mobile hydraulic systems. At 3.88 inches in overall length and 1.37 inches in both width and height, it fits in compact plumbing configurations. Licensed hydraulic technicians and fluid power specialists install this valve in systems where load holding or backflow prevention is required.

This check valve is suited for mobile equipment, industrial machinery, and hydraulic power unit applications where controlled unidirectional flow must be maintained. It is typically installed in pressure lines, return lines, or pilot circuits operating up to 3000 psi. The Female ORB thread standard ensures compatibility with standard SAE straight-thread O-ring fittings, making it a practical choice for new builds and service replacements in demanding hydraulic environments.

• Compact envelope at 3.88 x 1.37 x 1.37 inches for tight installation spaces

Compatibility

Designed as an OEM-style replacement or new-installation check valve for hydraulic systems using 1-1/16-12 Female ORB threaded connections operating at up to 3000 psi.

Installation Notes

Installation should be performed by a qualified fluid power technician or hydraulic systems specialist. Depressurize and lock out the hydraulic system completely before removing or installing any valve. Verify O-ring condition on mating fittings before torquing connections. Follow equipment manufacturer torque specifications and applicable fluid power standards for SAE O-ring Boss fittings.
