Parker 3C20EF-EF15 Hydraulic Check Valve 90 Gpm 3000 Psi

Product Description

The PARKER 3C20EF-EF15 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 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 integrates cleanly into standard hydraulic plumbing. At 5.76 inches in overall length and 2 inches in both width and height, it fits into compact hydraulic assemblies. This valve is installed by hydraulic system technicians and industrial maintenance professionals working on mobile or stationary hydraulic equipment.

This check valve is suited for use in industrial and mobile hydraulic systems where directional flow control and backflow prevention are required. Typical applications include hydraulic power units, cylinder circuits, and pressure-sensitive hydraulic lines where reverse flow could cause equipment damage or unsafe operating conditions. The female SAE thread connection makes it compatible with standard SAE hydraulic fittings commonly found in industrial and heavy-equipment hydraulic systems.

Key Features

• Maximum working pressure of 3000 psi for high-pressure hydraulic circuit use
• Maximum flow rate of 90 GPM to support high-volume hydraulic systems
• 1-5/8-12 female SAE threaded inlet for standard hydraulic plumbing integration
• Steel body construction for durability in demanding hydraulic environments
• Fluorocarbon seals for broad fluid compatibility and resistance to hydraulic fluid degradation
• Compact profile at 5.76 inches length and 2 inches width and height for space-constrained installations

Compatibility

Designed as an OEM-style replacement or direct-fit check valve for hydraulic systems using 1-5/8-12 female SAE threaded connections rated to 3000 psi working pressure.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Before servicing, depressurize the hydraulic system completely and relieve any stored energy in accumulators or cylinders. Use appropriate SAE hydraulic fittings and torque connections per the system manufacturer specifications. Verify flow direction markings on the valve body before final assembly to ensure correct orientation in the circuit.
