Parker F1220S Hydraulic Control Valve 25 Gpm 3000 Psi

Product Description

The PARKER F1220S is a hydraulic control valve designed for high-pressure fluid power systems. It accepts a 1-1/16-12 UNF threaded inlet, handles a maximum flow rate of 25 GPM, and is rated to 3,000 psi working pressure. The body is constructed from steel for durability under demanding industrial and mobile hydraulic conditions. Overall length is 4.62 inches and overall width is 1.38 inches. A knob-style handle provides manual flow control. Nitrile seals are used throughout, offering solid resistance to petroleum-based hydraulic fluids. This valve is installed by hydraulic system technicians and industrial maintenance professionals working on fluid power circuits.

The F1220S fits applications where manual control of hydraulic flow is required at pressures up to 3,000 psi. Typical installation scenarios include mobile equipment hydraulic circuits, industrial power units, and stationary hydraulic systems. The 1-1/16-12 UNF thread standard is common in medium- to high-pressure hydraulic plumbing, making this valve a practical fit for circuits using standard JIC or SAE fittings at that thread size. It is suited for both OEM builds and field replacement on systems requiring precise manual flow adjustment.

Key Features

• Maximum working pressure of 3,000 psi for high-pressure hydraulic circuits
• 25 GPM maximum flow rate supports medium- to high-flow system demands
• 1-1/16-12 UNF threaded inlet for standard hydraulic plumbing compatibility
• Steel body construction for strength and longevity in industrial environments
• Nitrile seals compatible with petroleum-based hydraulic fluids
• Knob handle allows manual flow control without additional tooling

Compatibility

Designed as an OEM-style replacement or new-installation hydraulic control valve for systems using 1-1/16-12 UNF threaded connections rated to 3,000 psi and 25 GPM maximum flow.

Installation Notes

Installation should be performed by a qualified hydraulic system technician. Depressurize and de-energize the hydraulic system completely before removing or installing any valve. Ensure all fittings are torqued to the system manufacturer's specifications using appropriate hydraulic wrenching tools. Verify seal compatibility with the system's hydraulic fluid before placing the valve in service.
