Parker DC-250-FOFO-5 Hydraulic Check Valve 8 Gpm

Product Description

The PARKER DC-250-FOFO-5 is a hydraulic control check valve designed to allow flow in one direction while preventing backflow in hydraulic circuit lines. Built with a steel body and metal seals, it handles demanding industrial and mobile hydraulic applications where pressure and leak integrity are critical. The valve accepts a 7/16-20 Female ORB (O-Ring Boss) inlet connection and is rated for a maximum working pressure of 3,000 psi and a maximum flow rate of 8 GPM. At 2.44 inches in overall length and 0.81 inches in both width and height, it fits into compact hydraulic manifold and inline plumbing configurations. Hydraulic technicians and fluid power specialists are the primary installers of this component.

This check valve is suited for inline hydraulic plumbing in residential lift equipment, industrial machinery, mobile equipment hydraulics, and similar systems requiring controlled unidirectional flow. The 7/16-20 Female ORB thread standard provides a reliable, leak-resistant connection commonly found on hydraulic pumps, cylinders, and valve blocks. Its compact envelope makes it practical for installations where space around the circuit is limited.

Key Features

• Maximum working pressure of 3,000 psi for high-pressure hydraulic circuit use
• Maximum flow rate of 8 GPM for moderate-duty hydraulic lines
• 7/16-20 Female ORB inlet thread for leak-resistant O-ring face sealing
• Steel body construction for durability in demanding fluid power environments
• Metal seal material rated for compatibility with standard hydraulic fluid media
• Compact 2.44 x 0.81 x 0.81 inch envelope for tight-clearance installations

Compatibility

Designed as an OEM-style replacement or service component for hydraulic systems requiring a 7/16-20 Female ORB check valve rated to 3,000 psi and 8 GPM.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and bleed the hydraulic system fully before removing or installing any valve component. Use the correct O-ring boss fittings and verify O-ring condition before torquing connections. Follow the equipment manufacturer and applicable NFPA fluid power standards for installation procedures and system startup.
