Parker C620S Hydraulic Control Valve 5 Gpm 5000 Psi

Product Description

The PARKER C620S is a one-way hydraulic flow control valve designed to regulate fluid flow in hydraulic circuits operating at high pressure. Built with a steel body and nitrile seals, it handles a maximum working pressure of 5000 psi and a maximum flow rate of 5 GPM. The 9/16-18 UNF threaded inlet and compact overall length of 3.12 inches make it suitable for tight installations where space and pressure integrity both matter. Licensed hydraulic technicians and industrial maintenance professionals typically install and service this valve type.

The C620S is suited for use in mobile hydraulic systems, industrial machinery, and hydraulic power units where one-way flow regulation is required. Its UNF thread standard and 9/16-inch inlet size place it in a common range of hydraulic circuit applications including actuator control, cylinder metering, and flow-sensitive motion circuits. It is packaged as a single unit and typically installed inline with standard hydraulic fittings.

Key Features

• One-way flow regulation for directional flow control in hydraulic circuits
• Maximum working pressure of 5000 psi for high-pressure system compatibility
• Maximum flow rate of 5 GPM
• 9/16-18 UNF threaded inlet for standard hydraulic plumbing
• Steel body construction for durability under pressure cycling
• Nitrile seals for compatibility with common hydraulic fluid types
• Compact overall length of 3.12 inches for space-constrained installations

Compatibility

Designed as an OEM-style replacement or inline flow control component for hydraulic systems using 9/16-18 UNF threaded connections rated to 5000 psi.

Installation Notes

Installation should be performed by a qualified hydraulic technician familiar with high-pressure fluid systems. Depressurize and de-energize the hydraulic circuit completely before removing or installing any valve component. Verify that system pressure and flow rates do not exceed the rated maximums for this valve. Inspect thread condition and use appropriate hydraulic thread sealant or fittings per system requirements.
