Parker 3C20F-F5A Hydraulic Check Valve 90 Gpm 3000 Psi

Product Description

The PARKER 3C20F-F5A is a hydraulic control check valve designed to allow fluid flow in one direction while blocking reverse flow in hydraulic circuits. Built with a steel body and nitrile seals, it handles a maximum working pressure of 3000 psi and a maximum flow rate of 90 GPM. The inlet connection is a 1-1/4-11-1/2 female NPTF thread, providing a pressure-tight seal without a separate sealant in many applications. At 3.021 pounds and measuring 5.76 inches in overall length, 2 inches in width, and 2 inches in height, this valve is compact enough for tight hydraulic panel installations. It is suited for industrial and mobile hydraulic systems where backflow prevention and pressure retention are required.

This valve is used in hydraulic power units, mobile equipment, and industrial machinery where controlled unidirectional flow is critical. Typical installation locations include return lines, load-holding circuits, and pump outlet lines in systems operating at pressures up to 3000 psi. The female NPTF threaded inlet makes it straightforward to integrate into existing threaded hydraulic manifolds or plumbing. It is installed by hydraulic system technicians and fluid power specialists working on both stationary and mobile equipment platforms.

Key Features

• Steel body construction for durability in high-pressure hydraulic environments
• Nitrile seal material compatible with standard petroleum-based hydraulic fluids
• Maximum working pressure of 3000 psi for demanding system requirements
• Maximum flow rate of 90 GPM suitable for medium to high-flow hydraulic circuits
• 1-1/4-11-1/2 female NPTF threaded inlet for a leak-resistant pressure-tight connection
• Compact form factor at 5.76 inches length and 2 inches width and height

Compatibility

Designed as an OEM-style replacement or direct-fit component for industrial and mobile hydraulic systems requiring a 1-1/4-inch female NPTF threaded check valve rated to 3000 psi and 90 GPM.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and isolate the hydraulic circuit completely before removing or installing any valves. NPTF threads are designed for dry-seal connections, but consult system specifications for guidance on thread sealant use. Verify that system operating pressure and flow rate do not exceed the valve ratings before returning the circuit to service.
