Parker DT-620-MSMS-5 Hydraulic Check Valve 15 Gpm

Product Description

The PARKER DT-620-MSMS-5 is a hydraulic control check valve designed for use in high-pressure hydraulic circuits. It controls flow direction, preventing reverse flow in the line while supporting a maximum working pressure of 5000 psi and a maximum flow rate of 15 GPM. The valve features a 1-14 Male Seal-Lok inlet thread and an all-steel body with metal seals, making it suited for demanding industrial and mobile hydraulic applications. At 1.74 inches in overall length with a compact 1.06 x 1.06 inch cross-section, it fits in tight manifold or plumbing configurations. Installation is handled by hydraulic system technicians and fluid power specialists.

This valve is intended for use in hydraulic power units, mobile equipment circuits, and industrial machinery where unidirectional flow control is required. The 1-14 Male Seal-Lok thread connection is a standard fitting type common in Parker hydraulic systems. Its compact envelope makes it a practical choice where space is limited and high-pressure ratings are required. It is sold individually and is appropriate for both OEM assembly and field service replacement applications.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and de-energize the hydraulic system completely before removing or installing any valve components. Ensure thread compatibility and use appropriate thread sealant or fitting practices per the system manufacturer and applicable fluid power standards. Verify flow direction marking on the valve body before final assembly.
