Parker DC-250-5 Hydraulic Check Valve 8 Gpm 3000 Psi

Product Description

The PARKER DC-250-5 is a hydraulic control check valve designed to permit flow in one direction while preventing backflow in hydraulic circuits. Built with a steel body and metal seals, it handles flow rates up to 8 GPM and working pressures up to 3,000 psi. The inlet thread is 1/4-18 Female NPSF, making it a compact, inline component suited for high-pressure hydraulic systems. Weighing 0.27 pounds with an overall length of 2.44 inches, this valve fits tight installation envelopes without sacrificing pressure integrity. It is typically installed by hydraulic system technicians and industrial maintenance professionals.

The DC-250-5 is suited for use in mobile hydraulic equipment, industrial machinery, and fluid power circuits where backflow prevention is required at moderate flow rates. Its compact 0.81-inch width and height allow installation in space-constrained manifold or inline configurations. The 1/4-18 Female NPSF thread is a standard connection in North American hydraulic plumbing, making this valve a straightforward drop-in solution for many existing circuit designs requiring reliable one-directional flow control at pressures up to 3,000 psi.

• 1/4-18 Female NPSF inlet thread — standard North American hydraulic connection
• Steel body construction with metal seals for durability in demanding environments
• Compact form factor: 2.44 inches long, 0.81 inches wide, 0.81 inches tall

Compatibility

Designed as an OEM-style replacement or service component for hydraulic circuits requiring a 1/4-18 Female NPSF inline check valve rated to 3,000 psi and 8 GPM.

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. Ensure thread sealant or tape is applied appropriately to the NPSF threads per standard hydraulic plumbing practice, and torque fittings per the equipment manufacturer's specifications. Verify flow direction arrow or port orientation before finalizing installation to ensure correct one-way flow function.
