Parker DC-500-5 Hydraulic Check Valve 40 Gpm 3000 Psi

Product Description

The PARKER DC-500-5 is a hydraulic control check valve designed to allow flow in one direction while preventing backflow in hydraulic circuits. Rated for a maximum working pressure of 3000 psi and a maximum flow rate of 40 GPM, this valve is built for demanding industrial and mobile hydraulic applications. The body is constructed from steel with metal seals, making it suitable for high-pressure environments where reliability and leak resistance are critical. The 1/2-14 female NPSF inlet provides a standard threaded connection for straightforward integration into existing hydraulic lines. Licensed hydraulic technicians and fluid power specialists are the primary installers of this component.

The DC-500-5 is used in hydraulic systems where controlled unidirectional flow is required, such as in mobile equipment, industrial machinery, and power unit assemblies. Its compact overall dimensions of 3.5 inches in length, 1.06 inches in width, and 1.06 inches in height allow installation in space-constrained manifold or inline configurations. The female NPSF thread standard makes it compatible with standard NPT-style hydraulic fittings commonly found in North American fluid power systems.

Key Features

• Maximum working pressure of 3000 psi for high-pressure hydraulic circuits
• Maximum flow rate of 40 GPM suits a wide range of hydraulic system demands
• Steel body construction provides durability in industrial and mobile applications
• Metal seal design for reliable, leak-resistant performance
• 1/2-14 female NPSF inlet for standard hydraulic line connection
• Compact form factor at 3.5 inches overall length for space-limited installations

Compatibility

Designed as an OEM-style replacement or direct-fit component for hydraulic systems requiring a 1/2-14 female NPSF threaded inline check valve rated to 3000 psi and 40 GPM.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Before servicing, depressurize the hydraulic system completely and verify that system pressure is at zero before removing or installing any valve. Use appropriate thread sealant compatible with hydraulic fluid and the NPSF thread form. Verify flow direction markings on the valve body before making final connections to ensure correct orientation in the circuit.
