Parker DT-500-MSMS-5 Hydraulic Check Valve 15 Gpm

Product Description

The PARKER DT-500-MSMS-5 is a hydraulic control check valve designed to allow flow in one direction while preventing backflow in hydraulic circuits. Built from steel with metal seals, it handles a maximum working pressure of 5000 psi and a maximum flow rate of 15 GPM. The inlet uses a 13/16-16 Male Seal-Lok thread standard, which provides a leak-resistant, face-seal connection common in high-pressure hydraulic lines. Its compact form factor — 1.52 inches overall length, 0.88 inches wide, and 0.88 inches tall — makes it suitable for tight plumbing configurations on mobile and industrial hydraulic systems. Hydraulic technicians and fluid power mechanics are the primary installers.

This check valve is intended for use in high-pressure hydraulic systems where backflow prevention is required. Typical applications include mobile equipment, industrial machinery, and hydraulic power units where consistent directional flow control is critical. The Male Seal-Lok connection provides a reliable, leak-free interface with compatible Seal-Lok or SAE O-ring face seal fittings. At 0.171 pounds, the valve is lightweight and easy to handle during installation in both new construction and retrofit hydraulic circuits.

Key Features

• Maximum working pressure of 5000 psi for demanding high-pressure hydraulic applications

• 13/16-16 Male Seal-Lok inlet thread for leak-resistant face-seal connections
• Steel body construction for durability in industrial and mobile equipment environments
• Metal seal material suitable for compatibility with a range of hydraulic fluids
• Compact size — 1.52 inches long, 0.88 inches wide, 0.88 inches tall — for tight installation spaces

Compatibility

Designed as an OEM-style hydraulic check valve for high-pressure hydraulic systems using 13/16-16 Male Seal-Lok connections rated up to 5000 psi.

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 the inlet and outlet thread standards on the host system match the 13/16-16 Male Seal-Lok specification before installation. Inspect all mating fittings and O-ring face seal surfaces for damage prior to torquing connections.
