Parker DT-370-MFMO-5 Hydraulic Check Valve 8 Gpm

Product Description

The PARKER DT-370-MFMO-5 is a hydraulic control check valve designed to allow flow in one direction while preventing backflow in hydraulic circuits. Built from steel with metal seals, it handles up to 8 GPM flow rate and a maximum working pressure of 5,000 psi. The valve uses a Male JIC x Male ORB thread configuration with a 9/16-18 inlet, making it a compact inline solution for mobile and industrial hydraulic systems. At 1.47 inches overall length and 0.75 inches in both height and width, it fits in space-constrained installations. Hydraulic technicians and fluid power specialists install this valve during new builds and repair work on hydraulic power units and circuit assemblies.

This valve is suited for use in mobile equipment, industrial machinery, and hydraulic power unit applications where directional flow control and backflow prevention are required. The Male JIC x Male ORB connection style is common in heavy equipment hydraulic lines, making this a direct-fit option for maintenance and retrofit work. Its compact body keeps plumbing tight where space is limited, and the all-steel construction handles the pressure demands typical of commercial and industrial hydraulic circuits.

Key Features

• Maximum working pressure of 5,000 psi suits high-pressure hydraulic circuits
• 8 GPM maximum flow rate supports standard mobile and industrial hydraulic applications
• Male JIC x Male ORB thread standard for broad hydraulic line compatibility
• Steel body construction for durability in demanding hydraulic environments
• Metal seal material provides reliable sealing at rated pressure
• Compact form factor at 1.47 inches length and 0.75 inches height and width

Compatibility

Designed as an OEM-style replacement or new-installation check valve for hydraulic circuits requiring a 9/16-18 Male JIC x Male ORB inline check valve rated to 5,000 psi.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and de-energize the hydraulic system fully before removing or installing any valve. Follow applicable industry standards for hydraulic fitting torque and thread engagement to avoid leaks at rated pressure. Inspect all mating fittings and lines for damage or contamination before reassembling the circuit.
