Parker DT-1000-MSMS-5 Hydraulic Check Valve 75 Gpm

Product Description

The PARKER DT-1000-MSMS-5 is a hydraulic control check valve designed to allow flow in one direction while preventing backflow in hydraulic circuits. Built with a steel body and metal seals, it handles working pressures up to 5,000 psi and flow rates up to 75 GPM, making it suitable for demanding mobile and industrial hydraulic applications. The 1-7/16-12 Male Seal-Lok inlet threading provides a leak-resistant connection common in high-pressure hydraulic lines. Licensed hydraulic technicians and fluid power specialists install this valve as part of actuator control circuits, cylinder lock-up systems, and directional control assemblies where reverse flow must be blocked.

This check valve fits into hydraulic systems requiring compact, in-line backflow prevention. It is well suited for mobile equipment, construction machinery, agricultural hydraulics, and industrial power units where high-pressure operation and reliable sealing are critical. With an overall length of 2.02 inches, a width of 1.5 inches, and a height of 1.5 inches, the compact envelope allows installation in tight plumbing configurations. The Male Seal-Lok thread standard is widely used in hydraulic fittings where face-seal connections are specified to eliminate thread-path leakage.

Key Features

• Maximum working pressure of 5,000 psi for high-pressure hydraulic circuit compatibility
• Maximum flow rate of 75 GPM to support high-volume system demands
• 1-7/16-12 Male Seal-Lok inlet for leak-resistant face-seal connections
• Steel body construction for durability in demanding hydraulic environments
• Metal seal material suitable for high-pressure and high-cycle applications
• Compact form factor at 2.02 inches long for space-constrained installations

Compatibility

Designed as an OEM-style replacement or service component for hydraulic systems utilizing 1-7/16-12 Male Seal-Lok porting and operating within 5,000 psi maximum working pressure and 75 GPM maximum flow rate parameters.

Installation Notes

Installation should be performed by a qualified fluid power technician or hydraulic systems specialist. Depressurize and de-energize the hydraulic system fully before removing or installing any valve component, and verify that residual accumulator pressure has been bled off. Confirm that the Male Seal-Lok fitting interfaces are clean and undamaged before torquing connections. Follow applicable machine manufacturer specifications and OSHA 1910.147 lockout/tagout procedures when servicing hydraulic circuits.
