Parker DC-750-FOFO-5 Check Valve 55 Gpm 3000 Psi

Product Description

The PARKER DC-750-FOFO-5 is a hydraulic control check valve designed to allow flow in one direction while preventing backflow in hydraulic circuits. Built with a steel body and metal seals, it is rated for a maximum working pressure of 3000 psi and a maximum flow rate of 55 GPM. The inlet uses a 1-1/16-12 Female ORB (O-Ring Boss) thread standard, making it compatible with standard hydraulic fittings found in industrial and mobile hydraulic systems. This valve is installed by hydraulic technicians and fluid power specialists maintaining or building high-pressure hydraulic lines and circuits.

The DC-750-FOFO-5 is suited for use in industrial machinery, mobile equipment, and other hydraulic power systems where backflow prevention and flow control are required. Its compact envelope and steel construction make it a practical choice for high-cycle hydraulic applications operating at or below 3000 psi. Typical installation scenarios include inline placement within pressure and return lines on construction equipment, agricultural machinery, and industrial hydraulic power units.

Key Features

• Maximum working pressure of 3000 psi for high-pressure hydraulic circuits
• Maximum flow rate of 55 GPM for high-volume line applications
• 1-1/16-12 Female ORB thread inlet for leak-resistant O-ring face seal connections
• Steel body construction for durability in demanding hydraulic environments
• Metal seals rated for compatibility with standard hydraulic fluids
• Compact overall dimensions support installation in space-constrained hydraulic assemblies

Compatibility

Designed as an OEM-style replacement or service component for hydraulic systems using 1-1/16-12 Female ORB porting rated to 3000 psi maximum working pressure and up to 55 GPM flow.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and de-energize the hydraulic system fully before removing any fittings or valves. Verify that thread type and port size match the existing circuit before installation, and inspect O-ring seals for damage prior to torqueing connections. Follow applicable OSHA and fluid power safety standards when working with high-pressure hydraulic systems.
