Parker C1220S Hydraulic Control Valve 25 Gpm 5000 Psi

Product Description

The PARKER C1220S is a one-way hydraulic control valve designed to regulate fluid flow in high-pressure hydraulic systems. Built with a steel body and nitrile seals, it handles a maximum working pressure of 5000 psi and a maximum flow rate of 25 GPM. The valve features a 1-1/16-12 UNF threaded inlet and measures 4.62 inches in overall length, making it suitable for inline installation in compact hydraulic circuits. Licensed hydraulic system technicians, industrial maintenance professionals, and mobile equipment mechanics typically install this component in fluid power applications where controlled, one-directional flow is required.

This valve is suited for use in industrial and mobile hydraulic systems where one-way flow regulation is critical to circuit performance. Typical applications include hydraulic power units, cylinder control circuits, and mobile equipment hydraulic systems operating at pressures up to 5000 psi. The 1-1/16-12 UNF thread standard ensures compatibility with standard SAE hydraulic fittings commonly found in these environments.

Key Features

• One-way flow regulation controls fluid direction in hydraulic circuits
• Maximum working pressure of 5000 psi for high-pressure system use
• Maximum flow rate of 25 GPM supports moderate to high-flow applications
• 1-1/16-12 UNF threaded inlet for compatibility with standard SAE hydraulic fittings
• Steel body construction provides durability in demanding hydraulic environments
• Nitrile seals offer resistance to petroleum-based hydraulic fluids

Compatibility

Designed as an OEM-style replacement or direct-fit valve for hydraulic systems using 1-1/16-12 UNF threaded connections and operating within 25 GPM and 5000 psi working parameters.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Depressurize and isolate the hydraulic circuit completely before removing or installing any valve components. Verify thread compatibility and apply appropriate thread sealant or O-ring face seal fittings per system design requirements. Torque fittings per the hydraulic system manufacturer specifications and inspect for leaks after returning the system to pressure.
