Parker N820S Hydraulic Control Valve 8 Gpm 5000 Psi

Product Description

The PARKER N820S is a hydraulic control valve designed to regulate flow in hydraulic systems operating at pressures up to 5,000 psi. Built with a steel body and nitrile seals, it handles a maximum flow rate of 8 GPM through a 3/4-inch inlet with a 3/4-16 UNF thread connection. The knob handle provides direct manual control for flow adjustment in the field. At 3 inches overall length and 1 inch overall width, it fits into compact hydraulic circuit assemblies. This valve is installed by hydraulic system technicians and fluid power specialists working on industrial and mobile hydraulic equipment.

The N820S is suited for use in hydraulic circuits that require manual flow control in industrial machinery, mobile equipment, and similar fluid power applications. Its UNF thread standard and 3/4-inch inlet size make it a direct-fit option for systems using standard hydraulic fittings at that port size. The 5,000 psi pressure rating supports high-pressure hydraulic circuits common in commercial and industrial service environments. A qualified hydraulic technician or fluid power mechanic is the typical installer for this type of valve.

Key Features

• Maximum working pressure of 5,000 psi for high-pressure hydraulic circuit use
• 8 GPM maximum flow rate handles moderate to high fluid volume demands
• Steel body construction provides durability in demanding hydraulic environments
• Nitrile seals offer compatibility with common hydraulic fluid types
• 3/4-16 UNF thread ensures compatibility with standard hydraulic port fittings
• Knob handle allows precise manual flow adjustment without additional tools

Compatibility

Designed as an OEM-style replacement or direct-fit control valve for hydraulic circuits using 3/4-inch UNF-threaded ports rated to 5,000 psi maximum working pressure.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power mechanic. Before servicing or installing this valve, fully depressurize and lock out the hydraulic system to prevent uncontrolled fluid release. Ensure thread sealant or fitting preparation is appropriate for the system fluid and pressure rating. Verify the inlet port thread size and system pressure rating match the valve specifications before completing installation.
