Parker DT-1250-MSMS-5 Hydraulic Check Valve 80 Gpm

Product Description

The PARKER DT-1250-MSMS-5 is a hydraulic control check valve designed for high-pressure fluid power systems. It allows flow in one direction only, preventing backflow and protecting downstream components from pressure surges or reverse flow events. Built with a steel body and metal seals, it is rated for a maximum working pressure of 4,000 psi and a maximum flow rate of 80 GPM. The 1-11/16-12 inlet uses Male Seal-Lok threading, providing a leak-resistant connection suited for demanding hydraulic circuits. Hydraulic technicians and fluid power specialists install this valve in mobile and industrial equipment applications.

This check valve is a fit for high-flow hydraulic circuits that require reliable one-way flow control at elevated pressures. The Male Seal-Lok thread standard is common in OEM and aftermarket hydraulic plumbing on construction, agricultural, and industrial machinery. At 80 GPM and 4,000 psi maximum working pressure, it handles heavy-duty duty cycles where backflow prevention is critical to system integrity and component longevity. Its compact envelope — 2.46 inches in length, 1.88 inches in width, and 1.88 inches in height — suits installations where space in the hydraulic manifold or plumbing circuit is limited.

Compatibility

Designed as a direct-fit hydraulic check valve for fluid power systems using 1-11/16-12 Male Seal-Lok port connections operating at up to 4,000 psi and 80 GPM.

Installation Notes

Installation should be performed by a qualified hydraulic technician familiar with fluid power system safety procedures. Depressurize and bleed the hydraulic circuit completely before removing any fittings or valves. Verify the Male Seal-Lok thread engagement and inspect sealing surfaces for damage before torquing connections. Confirm flow direction arrows or markings on the valve body align with the intended circuit flow path before bringing the system back to pressure.
