Parker DC-370-65 Hydraulic Check Valve 20 Gpm 3000 Psi

Product Description

The PARKER DC-370-65 is a hydraulic control check valve designed to allow flow in one direction and prevent backflow in hydraulic circuits. Built with a steel body and metal seals, it is rated for a maximum working pressure of 3000 psi and a maximum flow rate of 20 GPM. The inlet connection is a 3/8-18 Female NPSF thread, making it compatible with standard hydraulic line fittings. At 2.75 inches in length, 0.88 inches wide, and 0.88 inches tall, it is a compact unit suited for installation in tight hydraulic assemblies. This valve is typically installed by hydraulic system technicians and fluid power specialists working on industrial or mobile equipment.

The DC-370-65 is appropriate for use in hydraulic systems where load-holding, anti-drift, or backflow prevention is required. Typical applications include mobile hydraulic equipment, industrial machinery, and fluid power circuits operating at pressures up to 3000 psi. The 3/8-18 Female NPSF threaded inlet provides a secure connection to compatible hydraulic lines and fittings. Its compact overall envelope allows installation in manifold blocks or in-line configurations where space is limited.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and lock out the hydraulic system fully before removing or installing any valve. Use proper thread sealant rated for hydraulic service on all NPSF connections and torque fittings according to the system manufacturer specifications. Verify flow direction marking on the valve body before final installation to ensure correct orientation in the circuit.
