Parker 3C24EF-EF15A Hydraulic Check Valve 125 Gpm 3000 Psi

Product Description

The PARKER 3C24EF-EF15A is a hydraulic control check valve designed to allow flow in one direction and block reverse flow in hydraulic circuits. Built with a steel body and nitrile seals, it handles a maximum working pressure of 3,000 psi and a maximum flow rate of 125 GPM. The valve features a 1-7/8-12 female SAE inlet thread, making it suited for high-pressure hydraulic lines common in mobile and industrial applications. Licensed hydraulic system technicians and industrial maintenance mechanics typically specify and install this valve in fluid power circuits where backflow prevention and pressure holding are required.

This valve is used in hydraulic systems that require directional flow control and check functionality in a single body. Typical applications include mobile equipment hydraulics, industrial press circuits, and other high-pressure fluid power systems operating at or below 3,000 psi. Its compact envelope — 6.5 inches in overall length, 2.5 inches wide, and 2.5 inches tall — allows fitment in installations where space around the valve block is limited. The steel construction is appropriate for demanding duty cycles in both shop and field environments.

Key Features

• Maximum working pressure of 3,000 psi for high-pressure hydraulic circuit use
• Maximum flow rate of 125 GPM to support high-volume hydraulic circuits
• 1-7/8-12 female SAE inlet thread for secure, standardized hydraulic connections
• Steel body construction for durability in high-pressure and high-cycle applications
• Nitrile seals compatible with standard petroleum-based hydraulic fluids
• Compact dimensions — 6.5 inches length, 2.5 inches width, 2.5 inches height — for space-constrained installations

Compatibility

Designed as an OEM-style hydraulic control check valve for high-pressure fluid power systems requiring a 1-7/8-12 female SAE inlet connection and rated to 3,000 psi maximum working pressure.

Installation Notes

Installation should be performed by a qualified hydraulic systems technician or industrial mechanic familiar with fluid power circuit design. Depressurize and de-energize the hydraulic system fully before removing or installing any valve components. Verify that inlet thread engagement and torque conform to the equipment manufacturer's specifications and applicable fluid power standards. Inspect seals during installation and do not reuse damaged or compressed nitrile seals.
