Parker DC-750-5 Hydraulic Check Valve 55 Gpm 3000 Psi

Product Description

The PARKER DC-750-5 is a hydraulic control check valve designed to allow flow in one direction while preventing reverse flow in hydraulic systems. Built with a steel body and metal seals, it handles a maximum working pressure of 3000 psi and a maximum flow rate of 55 GPM. The 3/4-14 Female NPSF inlet threads into standard hydraulic line fittings. At 3.88 inches in overall length and 1.37 inches in both width and height, it fits into compact manifold or inline installations. Licensed hydraulic technicians and industrial maintenance mechanics typically install and service this component.

This check valve is suited for industrial and mobile hydraulic applications where backflow prevention is required at high operating pressures. It is appropriate for use in hydraulic power units, cylinder circuits, and directional control circuits where unidirectional flow control is essential. The steel body and metal seal construction make it compatible with a wide range of hydraulic fluids used in demanding operating environments. The compact envelope allows installation in space-constrained hydraulic assemblies on both stationary and mobile equipment.

Key Features

• Maximum working pressure of 3000 psi for high-pressure hydraulic circuit use
• Maximum flow rate of 55 GPM for medium-to-high flow applications
• 3/4-14 Female NPSF inlet for direct connection to standard hydraulic plumbing
• Steel body construction for durability in industrial service
• Metal seal for compatibility with a broad range of hydraulic fluids
• Compact footprint: 3.88 inches length, 1.37 inches width, 1.37 inches height

Compatibility

Designed as an OEM-style replacement or new-installation check valve for hydraulic systems requiring a 3/4-14 Female NPSF inlet, up to 55 GPM flow rate, and up to 3000 psi working pressure.

Installation Notes

Installation should be performed by a qualified hydraulic technician familiar with high-pressure fluid power systems. Depressurize and isolate the hydraulic circuit completely before removing or installing any valve. Verify that the system fluid and operating pressure are within the rated limits of this valve before returning the circuit to service. Follow applicable fluid power safety standards and the equipment manufacturer's service procedures when integrating this valve into a hydraulic circuit.
