Parker DC-1250-5 Hydraulic Check Valve 170 Gpm 3000 Psi

Product Description

The PARKER DC-1250-5 is a hydraulic control check valve designed to allow flow in one direction while blocking reverse flow in high-pressure hydraulic systems. Built with a steel body and metal seals, it is rated for a maximum working pressure of 3,000 psi and a maximum flow rate of 170 GPM. The 1-1/4-11-1/2 female NPTF inlet provides a pressure-tight threaded connection suited to demanding industrial and mobile hydraulic circuits. This valve is installed by hydraulic system technicians and maintenance professionals working on fluid power equipment where backflow prevention and pressure retention are critical.

The DC-1250-5 is suited for use in industrial hydraulic power units, mobile equipment hydraulics, and other high-pressure fluid power systems requiring reliable check valve performance. Its all-steel construction and metal seal make it appropriate for applications where compatibility with petroleum-based or synthetic hydraulic fluids is required and where elevated operating pressures are routine. The female NPTF thread standard ensures a leak-resistant connection without the need for additional sealant tape on properly gauged ports.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Depressurize and lock out the hydraulic system fully before removing or installing any valve components. Verify port thread engagement and torque to the hydraulic circuit manifold or plumbing specifications provided by the equipment manufacturer. Inspect mating threads and port faces for damage before assembly to maintain a leak-free connection at rated pressure.
