Parker DT-500-MFMO-5 Hydraulic Check Valve 15 Gpm

Product Description

The PARKER DT-500-MFMO-5 is a hydraulic control check valve designed to allow flow in one direction while preventing backflow in hydraulic circuits. Built with a steel body and metal seals, this valve handles maximum working pressures up to 4,500 psi and flow rates up to 15 GPM. The 3/4-16 inlet uses a Male JIC x Male ORB thread configuration for direct inline installation. Its compact envelope — 1.71 inches overall length, 0.88 inches wide, and 0.88 inches tall — makes it well-suited for tight hydraulic manifold assemblies and mobile equipment installations where space is limited.

This check valve is used in industrial and mobile hydraulic systems where backflow prevention is required to maintain circuit pressure or protect components from reverse flow. Typical applications include hydraulic power units, cylinders, motors, and directional control circuits on construction equipment, agricultural machinery, and industrial presses. Licensed hydraulic system technicians and fluid power specialists install this valve in both new construction and retrofit applications.

Key Features

• Steel body construction rated for up to 4,500 psi maximum working pressure
• Supports flow rates up to 15 GPM
• 3/4-16 inlet with Male JIC x Male ORB thread standard for reliable leak-free connections
• Metal seals for compatibility with hydraulic fluid at elevated pressures and temperatures
• Compact form factor: 1.71 inches length x 0.88 inches width x 0.88 inches height
• Lightweight at 0.163 pounds for weight-sensitive mobile applications

Compatibility

Designed as an OEM-style replacement or inline addition for hydraulic circuits requiring a 3/4-16 Male JIC x Male ORB check valve rated at 15 GPM and 4,500 psi. Verify thread type, pressure rating, and flow requirements against system specifications before installation.

Installation Notes

Installation should be performed by a qualified fluid power technician or hydraulic systems specialist. Depressurize and isolate the hydraulic circuit completely before removing or installing any valves. Inspect all JIC and ORB fittings for thread condition and ensure proper torque per the hydraulic fitting manufacturer specifications. Follow applicable industry standards such as SAE J514 for JIC connections and SAE J1453 for ORB port connections.
