Parker DC-750-65 Hydraulic Check Valve 55 Gpm 3000 Psi

Product Description

The PARKER DC-750-65 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 handles up to 55 GPM and a maximum working pressure of 3,000 psi. The inlet is a 3/4-14 Female NPSF thread. With overall dimensions of 3.88 inches in length, 1.37 inches in width, and 1.37 inches in height, this is a compact, robust valve suited for integration into demanding industrial hydraulic systems. It is installed by hydraulic system technicians and fluid power specialists working on mobile or stationary equipment.

This check valve is appropriate for use in hydraulic power units, mobile hydraulic circuits, and stationary industrial machinery where controlled, one-directional flow and backflow prevention are required. The 3/4-14 Female NPSF inlet connects directly to standard NPT-compatible hydraulic lines. Its steel construction and metal seal material make it suitable for high-pressure applications where elastomeric seals would be inadequate. This valve fits residential, commercial, and industrial hydraulic systems that operate within the 3,000 psi working pressure range.

Key Features

• Maximum flow rate of 55 GPM for high-capacity hydraulic circuits
• Rated to 3,000 psi maximum working pressure
• 3/4-14 Female NPSF inlet thread for standard hydraulic line connections
• Steel body construction for durability in high-pressure environments
• Metal seal material for compatibility with a wide range of hydraulic fluids
• Compact footprint: 3.88 inches long, 1.37 inches wide, 1.37 inches tall

Compatibility

Designed as an OEM-style replacement or direct-fit component for hydraulic systems requiring a 3/4-14 Female NPSF check valve rated to 3,000 psi and 55 GPM.

Installation Notes

Installation should be performed by a qualified fluid power technician or hydraulic system specialist. Depressurize and de-energize the hydraulic system fully before removing or installing any valve components. Use appropriate thread sealant rated for hydraulic service on NPSF connections and verify torque requirements against the system manufacturer's specifications. Confirm inlet flow direction prior to installation to ensure proper check valve orientation.
