Parker DC-370-FOFO-5 Hydraulic Check Valve 20 Gpm

Product Description

The PARKER DC-370-FOFO-5 is a hydraulic control check valve designed to allow flow in one direction while preventing reverse flow in hydraulic circuits. Built with a steel body and metal seals, this valve is rated for a maximum working pressure of 3000 psi and a maximum flow rate of 20 GPM. The 9/16-18 female ORB (O-Ring Boss) inlet threading provides a leak-resistant, reliable connection common in mobile and industrial hydraulic systems. At 2.75 inches overall length and 0.88 inches in both height and width, it fits into compact manifold or inline installations. Licensed hydraulic technicians and fluid power specialists are the typical installers.

This check valve is suited for use in mobile equipment, industrial machinery, and hydraulic power units where backflow prevention is required. The female ORB port configuration makes it compatible with standard SAE straight-thread O-ring fittings found throughout mobile hydraulics, construction equipment hydraulics, and stationary power unit plumbing. It is appropriate for both new installations and replacement service work where a rated 3000 psi single-direction flow control device is specified.

Key Features

• Maximum working pressure of 3000 psi for high-pressure hydraulic circuit use
• Maximum flow rate of 20 GPM suitable for medium-duty hydraulic applications
• 9/16-18 female ORB inlet threading for leak-resistant O-ring face seal connections
• Steel body construction for durability in demanding hydraulic environments
• Metal seals rated for compatibility with common hydraulic fluid types
• Compact footprint at 2.75 inches length and 0.88 inches height and width for tight installations

Compatibility

Designed as an OEM-style replacement or new-installation check valve for hydraulic systems utilizing 9/16-18 female ORB port connections rated to 3000 psi working pressure.

Installation Notes

Installation should be performed by a qualified fluid power technician or hydraulic systems professional. Depressurize and bleed the hydraulic system fully before removing any fittings or valves. Verify that all port threads and O-ring seating surfaces are clean and undamaged before torquing fittings. Follow the equipment manufacturer's specifications and applicable fluid power standards for fitting torque and system pressure testing after installation.
