Parker DC-370-5 Hydraulic Check Valve 20 Gpm 3000 Psi

Product Description

The PARKER DC-370-5 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, it handles a maximum working pressure of 3000 psi and a maximum flow rate of 20 GPM. The 3/8-18 female NPSF threaded inlet makes it compatible with standard hydraulic plumbing connections. This valve is installed by hydraulic system technicians and maintenance professionals working on industrial, mobile, or stationary hydraulic equipment where backflow prevention and circuit control are required.

This check valve is suited for use in hydraulic power units, mobile equipment hydraulic systems, and industrial machinery where controlled directional flow is essential. Its compact dimensions of 2.75 inches overall length, 0.88 inches width, and 0.88 inches height allow installation in tight hydraulic manifold or inline plumbing configurations. The metal-to-metal seal construction makes it appropriate for high-pressure applications where elastomeric seals may not be suitable.

Key Features

• Maximum working pressure of 3000 psi for high-pressure hydraulic circuit use
• Maximum flow rate of 20 GPM to handle typical industrial and mobile hydraulic demands
• 3/8-18 female NPSF threaded inlet for standard hydraulic plumbing compatibility
• Steel body construction for durability in demanding hydraulic environments
• Metal seal material suitable for high-pressure and high-temperature service
• Compact profile at 2.75 inches long by 0.88 inches in height and width

Compatibility

Designed as an OEM-style replacement or new-installation check valve for hydraulic systems using 3/8-18 female NPSF threaded connections rated to 3000 psi and 20 GPM maximum flow.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Before servicing any hydraulic component, fully depressurize the system and verify zero pressure at the work point using a calibrated gauge. Use appropriate thread sealant rated for hydraulic service on NPSF connections and avoid over-torquing to prevent thread damage in the steel body. Verify flow direction markings on the valve body before completing the installation to ensure proper check function.
