Parker DC-1250-65 Hydraulic Check Valve 170 Gpm 3000 Psi

Product Description

The PARKER DC-1250-65 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, this valve handles up to 170 GPM and a maximum working pressure of 3,000 psi. The inlet is sized at 1-1/4 inch with 11-1/2 Female NPTF threading, making it a direct-thread, no-adapter installation in standard NPT hydraulic plumbing. Overall dimensions are 5.94 inches in length, 2 inches in width, and 2 inches in height. The unit weighs 3.39 pounds. Hydraulic technicians and fluid power mechanics install this valve in mobile and industrial hydraulic systems where backflow prevention and pressure holding are required.

This check valve is suited for use in industrial and mobile hydraulic applications where controlled one-directional flow is critical. Typical installation scenarios include hydraulic power units, cylinders, manifolds, and circuit protection on hydraulic presses, lifts, and work-holding equipment. The Female NPTF inlet provides a pressure-rated threaded connection compatible with standard hydraulic piping and fittings. The all-steel construction and metal seal make it appropriate for higher-temperature and higher-pressure service environments where elastomeric seals would be a limiting factor.

Key Features

• Maximum flow rate of 170 GPM supports high-volume hydraulic circuit demand
• Rated to 3,000 psi maximum working pressure for industrial-grade service
• 1-1/4 inch 11-1/2 Female NPTF inlet for direct threaded connection
• Steel body construction for durability in demanding hydraulic environments
• Metal seal material for high-temperature and high-pressure compatibility
• Compact envelope at 5.94 inches length and 2 inches height and width

Compatibility

Designed as an OEM-style hydraulic check valve for use in industrial and mobile hydraulic systems plumbed with 1-1/4 inch Female NPTF connections and operating within 170 GPM and 3,000 psi service limits.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power mechanic. De-pressurize and de-energize the hydraulic system fully before removing or installing any valve. Inspect all NPTF threads for damage before assembly and apply an appropriate thread sealant rated for hydraulic service. Verify flow direction markings on the valve body before final installation to ensure correct check orientation in the circuit.
