Parker C1020S Hydraulic Control Valve 15 Gpm 5000 Psi

Product Description

The PARKER C1020S is a one-way hydraulic control valve designed to regulate fluid flow in hydraulic circuits. Built with a steel body and nitrile seals, it handles working pressures up to 5,000 psi and flow rates up to 15 GPM. The valve features a 7/8-14 UNF threaded inlet and measures 4 inches overall in length, making it a compact, direct-fit solution for mobile and industrial hydraulic systems. Hydraulic technicians and fluid power specialists install this valve where precise one-way flow regulation is required in high-pressure lines.

The C1020S suits residential and commercial hydraulic applications where controlled directional flow is critical. Typical installations include mobile equipment hydraulics, industrial machinery, and agricultural equipment that demand reliable pressure management at sustained working loads. The 7/8-14 UNF thread standard ensures compatibility with common SAE hydraulic fittings used across a wide range of equipment platforms.

Key Features

• One-way flow regulation for directional hydraulic circuit control
• Maximum working pressure of 5,000 psi for demanding high-pressure applications
• Maximum flow rate of 15 GPM to match common mid-range hydraulic system requirements
• Steel body construction for durability in high-pressure environments
• Nitrile seals rated for compatibility with standard hydraulic fluids
• Compact 4 inch overall length for installation in space-constrained hydraulic assemblies

Compatibility

Designed as an OEM-style replacement or new-installation hydraulic control valve for systems using 7/8-14 UNF threaded hydraulic fittings with operating pressures up to 5,000 psi and flow rates up to 15 GPM.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Before servicing any hydraulic component, fully depressurize the system and relieve all stored hydraulic pressure. Ensure thread engagement meets applicable standards and use appropriate thread sealant compatible with hydraulic fluid. Verify that system pressure and flow rates do not exceed the valve's rated maximums during operation.
