Parker DT-750-MSMS-5 Hydraulic Check Valve 30 Gpm

Product Description

The PARKER DT-750-MSMS-5 is a hydraulic control check valve designed to permit flow in one direction while blocking reverse flow in hydraulic circuits. Built from steel with metal seals, it handles a maximum working pressure of 5000 psi and a maximum flow rate of 30 GPM. The 1-3/16-12 Male Seal-Lok inlet thread provides a leak-resistant, bite-type face seal connection suited to high-pressure hydraulic plumbing. Compact overall dimensions of 1.86 inches length, 1.25 inches width, and 1.25 inches height make it practical for tight manifold or inline installations. Licensed hydraulic technicians and industrial maintenance professionals are the typical installers of this component.

This check valve is appropriate for use in mobile hydraulic systems, industrial hydraulic power units, and similar high-pressure fluid power circuits requiring reliable unidirectional flow control. The Male Seal-Lok (MSMS) fitting style is commonly found on heavy equipment, agricultural machinery, construction equipment, and industrial machine tool hydraulic circuits. Its all-steel construction and metal seal make it suitable for demanding duty cycles where elastomeric seals would be insufficient.

Key Features

• Maximum working pressure of 5000 psi for high-pressure hydraulic applications
• Maximum flow rate of 30 GPM to support high-volume hydraulic circuits
• 1-3/16-12 Male Seal-Lok (MSMS) thread for leak-resistant face seal connections
• Steel body construction for durability in demanding hydraulic environments
• Metal seal material suited for high-pressure and high-temperature service
• Compact form factor at 1.86 x 1.25 x 1.25 inches for space-constrained installations

Compatibility

Designed as an OEM-style replacement or service component for hydraulic systems utilizing 1-3/16-12 Male Seal-Lok porting and rated to 5000 psi working pressure.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Before servicing, fully depressurize the hydraulic circuit and relieve any stored energy in accumulators or actuators. Male Seal-Lok fittings rely on a face seal rather than thread engagement for leak prevention — ensure mating surfaces are clean and free of damage before torquing. Follow the equipment manufacturer's plumbing specifications and applicable fluid power standards for proper assembly.
