Parker DT-250-MFMO-5 Hydraulic Check Valve 2 Gpm 5000 Psi

Product Description

The PARKER DT-250-MFMO-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 system pressures up to 5,000 psi and flow rates up to 2 GPM. The compact form factor — 1.42 inches in overall length, 0.63 inches wide, and 0.63 inches tall — makes it well suited for installations where space is limited. The 7/16-20 Male JIC x Male ORB thread configuration allows direct inline installation without additional adapters in compatible porting configurations. This valve is installed by hydraulic technicians and fluid power specialists working on mobile or industrial hydraulic systems.

This check valve is used in hydraulic circuits that require backflow prevention at low flow rates. Typical applications include mobile equipment hydraulics, compact power units, and industrial machinery where controlled directional flow must be maintained at elevated pressures. The metal seal construction makes it appropriate for systems where elastomeric seals would be incompatible with the hydraulic fluid or operating temperature range. Its small overall envelope allows placement in tight manifold or inline positions.

Key Features

• Maximum working pressure of 5,000 psi for high-pressure hydraulic circuit use
• Maximum flow rate of 2 GPM suitable for low-flow control applications
• Steel body construction for durability in demanding hydraulic environments
• Metal seal for compatibility with a wide range of hydraulic fluids and temperatures
• 7/16-20 Male JIC x Male ORB thread standard for direct inline installation
• Compact dimensions — 1.42 inches long by 0.63 inches wide by 0.63 inches tall

Compatibility

Designed as an OEM-style inline check valve for hydraulic systems using 7/16-20 Male JIC x Male ORB porting with operating pressures up to 5,000 psi and flow rates at or below 2 GPM.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Depressurize and isolate the hydraulic circuit fully before removing or installing any valve. Verify thread compatibility and torque fittings to the hydraulic system manufacturer's specifications for the JIC and ORB port standards. Confirm flow direction arrow or valve orientation before final assembly to ensure correct check function.
