Parker DT-620-MOMF-5 Hydraulic Check Valve 15 Gpm

Product Description

The PARKER DT-620-MOMF-5 is a hydraulic control check valve designed to allow flow in one direction while preventing backflow in hydraulic circuit applications. Built with a steel body and metal seals, it handles operating pressures up to 5,000 psi and flow rates up to 15 GPM. The compact envelope measures 1.89 inches in length, 1.06 inches in width, and 1.06 inches in height, making it well suited for tight installations on mobile equipment, industrial machinery, and hydraulic power units. Connections follow a Male ORB x Male JIC thread standard using a 7/8-14 inlet. This valve is installed by hydraulic system technicians and fluid power specialists.

This check valve fits into hydraulic circuits where directional flow control and backflow prevention are required. Its all-metal sealing construction makes it appropriate for higher-temperature or contamination-sensitive circuits where elastomeric seals may not be suitable. Typical install scenarios include mobile hydraulic systems on agricultural and construction equipment, industrial hydraulic power units, and plumbing circuits requiring inline backflow protection at pressures up to 5,000 psi.

Key Features

• Rated for up to 5,000 psi maximum working pressure
• Maximum flow rate of 15 GPM
• Male ORB x Male JIC thread configuration with 7/8-14 inlet size
• Steel body construction for durability in high-pressure environments
• Metal seal material suitable for high-temperature and contamination-sensitive applications

Compatibility

Designed as an OEM-style replacement or direct-fit component for hydraulic circuits requiring a Male ORB x Male JIC check valve rated at 15 GPM and 5,000 psi.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and isolate the hydraulic circuit fully before removing or installing any valve. Verify thread compatibility and use appropriate hydraulic fittings and thread sealant per the equipment manufacturer specifications. Torque fittings according to the hydraulic system or fitting manufacturer guidelines — do not over-torque steel fittings into ported manifolds.
