Parker 3C20EF-EF65 Hydraulic Check Valve 90 Gpm 3000 Psi

Product Description

The PARKER 3C20EF-EF65 is a hydraulic control check valve rated for up to 90 GPM flow and a maximum working pressure of 3,000 psi. Built from steel with a fluorocarbon seal, it is designed for demanding hydraulic circuit applications where backflow prevention and precise flow control are required. The inlet is a 1-5/8-12 female SAE threaded connection. Overall dimensions are 5.76 inches in length, 2 inches in width, and 2 inches in height, with a package weight of 3.126 pounds. This valve is typically installed by hydraulic system technicians and fluid power specialists working on industrial or mobile hydraulic circuits.

This check valve suits residential, commercial, and industrial hydraulic systems where controlled unidirectional flow is critical. It is appropriate for high-pressure hydraulic lines in mobile equipment, industrial machinery, and power unit assemblies. The female SAE thread standard makes it compatible with standard SAE hydraulic plumbing configurations. Its steel body construction handles the mechanical stress of continuous high-pressure cycling common in production and field service environments.

Key Features

• Maximum flow rate of 90 GPM supports high-volume hydraulic circuits
• Rated to 3,000 psi maximum working pressure for heavy-duty applications
• 1-5/8-12 female SAE threaded inlet for standard hydraulic plumbing compatibility
• Steel body construction for durability under high-pressure cycling
• Fluorocarbon seal material for resistance to hydraulic fluid degradation
• Compact envelope: 5.76 inches long, 2 inches wide, 2 inches tall

Compatibility

Designed as an OEM-style replacement or direct-fit component for hydraulic systems using 1-5/8-12 female SAE threaded connections and operating within 90 GPM and 3,000 psi design parameters.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Before servicing, depressurize the hydraulic circuit completely and relieve any stored accumulator pressure. Use appropriate thread sealant rated for hydraulic service and ensure proper torque on SAE fittings per the system manufacturer's specifications. Verify flow direction markings on the valve body before final installation to ensure correct unidirectional operation.
