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

Product Description

The PARKER DT-1000-MFMF-5 is a hydraulic control check valve designed to allow unidirectional flow while preventing backflow in hydraulic circuits. Built with a steel body and metal seals, it handles flow rates up to 75 GPM and working pressures up to 3,000 psi. The valve measures 2.44 inches in overall length, 1.5 inches in width, and 1.5 inches in height, making it a compact, inline component suited for high-pressure hydraulic systems. It is installed by hydraulic technicians and industrial mechanics on mobile equipment, industrial machinery, and fluid power circuits requiring reliable check valve performance.

This valve fits applications where backflow prevention is critical in high-pressure hydraulic lines. The 1-5/16-12 Male JIC inlet threading makes it compatible with standard JIC hydraulic fittings commonly found in mobile hydraulics, construction equipment, and industrial fluid power systems. Its steel construction and metal seal design make it appropriate for use in demanding environments where temperature fluctuations and high cycle counts are expected. Technicians specify this valve as a direct inline component in circuits requiring 75 GPM capacity at up to 3,000 psi working pressure.

Key Features

• Maximum flow rate of 75 GPM supports high-demand hydraulic circuits
• Rated to 3,000 psi maximum working pressure for heavy-duty applications
• 1-5/16-12 Male JIC inlet threading for standard JIC hydraulic line connections
• Steel body construction provides durability in high-cycle and high-pressure environments
• Metal seal material for compatibility with a wide range of hydraulic fluids
• Compact form factor at 2.44 inches long, 1.5 inches wide, and 1.5 inches tall

Compatibility

Designed as an OEM-style inline check valve for hydraulic systems using 1-5/16-12 Male JIC fittings operating within 75 GPM flow and 3,000 psi pressure ratings.

Installation Notes

Installation should be performed by a qualified hydraulic technician familiar with fluid power systems. Depressurize and isolate the hydraulic circuit fully before removing or installing any valve. Verify thread engagement and use appropriate hydraulic thread sealant or dry-seal JIC fittings as required by the system design. Confirm flow direction markings on the valve body before final assembly to ensure correct check valve orientation.
