Parker DT-500-MSMO-65 Hydraulic Check Valve 15 Gpm

Product Description

The PARKER DT-500-MSMO-65 is a hydraulic control check valve designed for high-pressure fluid circuits in mobile and industrial hydraulic systems. It controls flow direction, preventing backflow and protecting downstream components from pressure surges. Rated to 5,000 psi maximum working pressure and 15 GPM maximum flow rate, it is built for demanding duty cycles. The body is steel construction with metal seals, making it well suited for high-cycle applications where elastomeric seals would degrade. Connections follow the Male Seal-Lok by Male ORB thread standard, which is standard in hydraulic plumbing for leak-free assembly. Licensed hydraulic technicians and fluid power specialists are the typical installers for this type of fitting-mounted valve.

The DT-500-MSMO-65 fits into inline hydraulic circuits where directional flow control and backflow prevention are required. Its compact overall dimensions of 1.56 inches length by 0.88 inches width by 0.88 inches height make it suitable for tight manifold or fitting installations on construction equipment, agricultural machinery, and industrial power units. The 13/16-16 inlet size is a common SAE port size found across a wide range of hydraulic actuator and pump circuit configurations. This valve is appropriate for both new installations and replacement work in existing hydraulic assemblies.

Key Features

• 5,000 psi maximum working pressure for high-pressure hydraulic circuits
• 15 GPM maximum flow rate supports moderate-to-high flow applications
• Steel body construction for durability in demanding duty environments
• Metal seal material rated for high-cycle and high-temperature service
• Male Seal-Lok x Male ORB thread standard for leak-free hydraulic connections
• Compact profile at 1.56 inches OAL for installation in confined spaces

Compatibility

Designed as an OEM-style replacement or new-installation check valve for hydraulic systems using 13/16-16 Male Seal-Lok by Male ORB threaded ports operating at up to 5,000 psi and 15 GPM.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Before servicing any hydraulic component, depressurize the entire hydraulic circuit and verify zero pressure with a gauge before disconnecting fittings. Torque fittings according to the system manufacturer's hydraulic assembly specifications for the thread standard in use. Inspect all port threads and seating surfaces for damage prior to installation to ensure a leak-free seal.
