Parker 3C20EF-EF5 Hydraulic Check Valve 90 Gpm 3000 Psi

Product Description

The PARKER 3C20EF-EF5 is a hydraulic control check valve designed to allow flow in one direction while preventing backflow in hydraulic systems. Built from steel with fluorocarbon seals, it handles a maximum working pressure of 3000 psi and a maximum flow rate of 90 GPM. The 1-5/8-12 female SAE threaded inlet provides a secure, leak-resistant connection compatible with standard hydraulic plumbing. At 5.76 inches in overall length and 2 inches in both width and height, the unit is compact enough for installation in tight hydraulic manifold assemblies or inline plumbing runs. This valve is installed by hydraulic system technicians and industrial maintenance professionals working on mobile or stationary hydraulic equipment.

The 3C20EF-EF5 is suited for use in industrial and mobile hydraulic circuits where controlled unidirectional flow and backflow prevention are required. Typical applications include hydraulic cylinders, motor circuits, and pressure-holding systems operating at or below 3000 psi. The female SAE thread standard makes it a straightforward fit for existing hydraulic plumbing that uses SAE straight-thread or compatible fittings. The fluorocarbon seal material offers resistance to a wide range of hydraulic fluids, making it appropriate for systems using petroleum-based or synthetic hydraulic oil.

Compatibility

Designed as an OEM-style replacement or direct-install control check valve for hydraulic systems utilizing 1-5/8-12 female SAE threaded connections and operating within 90 GPM and 3000 psi ratings.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Depressurize and isolate the hydraulic circuit fully before removing any fittings or installing this valve. Verify that the system fluid type is compatible with fluorocarbon seal material prior to installation. Torque all fittings according to the equipment manufacturer specifications and inspect for leaks before returning the system to service.
