Parker DT-750-MSMS-65 Hydraulic Check Valve 30 Gpm

Product Description

The PARKER DT-750-MSMS-65 is a hydraulic control check valve designed to allow flow in one direction while preventing reverse flow in hydraulic circuits. Built with a steel body and metal seals, this valve handles up to 5,000 psi working pressure and a maximum flow rate of 30 GPM. The 1-3/16-12 inlet uses a Male Seal-Lok thread standard, providing a reliable leak-resistant connection common in industrial and mobile hydraulic systems. At 1.86 inches overall length and 1.25 inches in both height and width, this is a compact inline component suited for tight plumbing configurations. Hydraulic technicians and fluid power specialists install this valve in both stationary and mobile equipment applications.

This check valve is used in hydraulic systems where backflow prevention is critical to circuit integrity and actuator holding performance. Typical installation scenarios include mobile equipment, industrial machinery, and hydraulic power units where consistent one-directional flow control is required. The Male Seal-Lok thread connection is standard in many medium- and high-pressure hydraulic plumbing assemblies, making this valve a straightforward fit for systems already using that thread standard. It is packaged as a single unit and sold individually.

Key Features

• Prevents reverse flow in hydraulic circuits up to 5,000 psi
• 30 GPM maximum flow rate supports medium- to high-flow applications
• 1-3/16-12 Male Seal-Lok inlet for secure, leak-resistant connections
• Steel body construction for durability in high-pressure environments
• Metal seal material rated for demanding hydraulic service
• Compact form factor at 1.86 x 1.25 x 1.25 inches for space-constrained plumbing

Compatibility

Designed as an OEM-style replacement or new-installation check valve for hydraulic systems using 1-3/16-12 Male Seal-Lok thread connections operating at up to 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 any fittings or installing this valve. Verify thread compatibility and torque fittings to the hydraulic system manufacturer's specifications using appropriate hydraulic wrenches. Confirm flow direction arrow or inlet/outlet orientation before final assembly to ensure correct check function.
