Parker DC-500-FOFO-5 Hydraulic Check Valve 40 Gpm

Product Description

The PARKER DC-500-FOFO-5 is a hydraulic control check valve designed to allow flow in one direction while preventing reverse flow in hydraulic circuits. Built from steel with metal seals, it handles maximum working pressures up to 3000 psi and supports flow rates up to 40 GPM. The 3/4-16 female ORB inlet threading makes it compatible with standard hydraulic fittings found in industrial and mobile equipment systems. At 3.5 inches in overall length and 0.594 pounds, it is compact and straightforward to integrate into existing hydraulic manifolds or inline plumbing assemblies. Licensed hydraulic technicians and fluid power specialists are the primary installers of this component.

This valve is suited for industrial hydraulic systems and mobile equipment applications where controlled unidirectional flow management is required. It fits inline hydraulic circuits operating at high pressure. The female ORB thread standard ensures a reliable, leak-resistant connection. Typical use cases include press systems, lift circuits, and directional control assemblies where load holding or flow isolation is critical to safe and consistent operation.

Key Features

• Maximum working pressure of 3000 psi for high-pressure hydraulic systems
• Maximum flow rate of 40 GPM to support high-volume circuits
• 3/4-16 female ORB inlet for leak-resistant, standardized connections
• Steel body construction for durability in demanding hydraulic environments
• Metal seal material for high-pressure compatibility and long service life
• Compact profile at 3.5 inches overall length and 1.06 inches in width and height

Compatibility

Designed as an OEM-style hydraulic check valve for high-pressure hydraulic circuits requiring a 3/4-16 female ORB inlet connection and rated for up to 3000 psi and 40 GPM flow capacity.

Installation Notes

Installation should be performed by a qualified fluid power technician or hydraulic systems professional. Depressurize and isolate the hydraulic circuit completely before removing or installing any valve components. Verify that the system operating pressure and flow rate do not exceed the rated limits of this valve. Ensure all fittings are properly torqued to manufacturer specifications for the female ORB thread standard to prevent leaks under pressure.
