Parker DT-1250-MSMO-5 Hydraulic Check Valve 80 Gpm

Product Description

The PARKER DT-1250-MSMO-5 is a hydraulic control check valve designed to allow flow in one direction while preventing backflow in hydraulic circuit lines. Built from steel with a metal seal, this valve handles up to 80 GPM flow rate and a maximum working pressure of 4,000 psi. The inlet is threaded 1-11/16-12 with a Male Seal-Lok x Male ORB connection standard, making it compatible with common hydraulic fitting configurations. At 2.49 inches in overall length and a compact 1.88-inch width and height profile, it fits in tight plumbing runs. Licensed hydraulic technicians and industrial maintenance professionals are the typical installers for this type of inline check component.

This check valve is suited for industrial and mobile hydraulic systems where backflow prevention is required in medium-to-high pressure circuits. Typical applications include hydraulic power units, mobile equipment, and fixed industrial machinery where circuit integrity must be maintained when pressure fluctuates or the pump is offline. The Male Seal-Lok x Male ORB thread configuration suits standard hydraulic plumbing practices across a range of OEM and aftermarket hydraulic systems.

Key Features

• Maximum flow rate of 80 GPM supports medium-to-high volume hydraulic circuits
• Rated to 4,000 psi maximum working pressure for demanding industrial applications
• Steel body construction provides durability in high-pressure environments
• Metal seal material for compatibility with a wide range of hydraulic fluids
• Male Seal-Lok x Male ORB thread standard for leak-resistant, standardized connections
• Compact overall dimensions allow installation in space-constrained hydraulic plumbing runs

Compatibility

Designed as an OEM-style replacement or direct-fit check valve for hydraulic systems utilizing 1-11/16-12 inlet connections with Male Seal-Lok x Male ORB thread configurations operating within 80 GPM and 4,000 psi working pressure limits.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Fully depressurize and de-energize the hydraulic system before removing any fittings or installing this valve. Verify thread type and torque fittings to the hydraulic system manufacturer's published specifications for Seal-Lok and ORB connections. Confirm flow direction arrow or valve orientation matches the intended circuit flow path before returning the system to service.
