Parker DC-250-65 Hydraulic Check Valve 8 Gpm 3000 Psi

Product Description

The PARKER DC-250-65 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, this valve handles up to 3,000 psi working pressure and flows up to 8 GPM. The compact profile measures 2.44 inches in overall length, 0.81 inches in width, and 0.81 inches in height, making it suitable for tight installation envelopes. The 1/4-18 Female NPSF threaded inlet provides a secure, leak-resistant connection. Hydraulic mechanics and fluid power technicians install this valve in mobile and industrial hydraulic circuits where backflow prevention is required.

This check valve fits into hydraulic control circuits found in industrial machinery, mobile equipment, and power unit assemblies. The 1/4-18 Female NPSF thread is a standard fitting in many North American hydraulic systems, making this valve a practical fit for maintenance and replacement work. Its all-steel, metal-seal construction suits environments where fluid compatibility with rubber seals is a concern or where elevated pressure cycles demand a durable seat. The small form factor allows installation in manifold blocks, in-line plumbing, or directional control circuits where space is limited.

Key Features

• Maximum working pressure of 3,000 psi for demanding hydraulic circuit applications
• Maximum flow rate of 8 GPM through a 1/4-18 Female NPSF inlet
• Steel body construction for durability under pressure and mechanical stress
• Metal seal material suitable for high-cycle or fluid-compatibility-sensitive applications
• Compact dimensions — 2.44 inches long, 0.81 inches wide, 0.81 inches tall — for tight-space installs
• Lightweight at 0.22 pounds, minimizing added load in mobile equipment plumbing

Compatibility

Designed as an OEM-style hydraulic check valve for use in hydraulic circuits requiring a 1/4-18 Female NPSF threaded connection with a maximum working pressure rating of 3,000 psi and flow capacity up to 8 GPM.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power mechanic. Depressurize and isolate the hydraulic circuit completely before removing or installing any valve. Verify that thread type and size match the port before installation to avoid cross-threading or fitting mismatch. Follow applicable hydraulic system safety standards and equipment manufacturer guidelines for torque and line preparation procedures.
