Parker C820S Hydraulic Control Valve 8 Gpm 5000 Psi

Product Description

The PARKER C820S is a one-way hydraulic control valve designed for use in hydraulic power and fluid control systems. It features a 3/4-inch inlet with a 3/4-16 UNF thread and handles a maximum flow rate of 8 GPM at up to 5,000 psi working pressure. The steel body provides durability under high-pressure cycling, while the nitrile seals resist hydraulic fluid degradation. At 3.5 inches overall length and 0.7 pounds, the C820S is compact enough for tight installation envelopes. This valve is installed by hydraulic system technicians, maintenance mechanics, and fluid power specialists working on industrial and mobile hydraulic equipment.

The C820S is suited for applications requiring controlled one-way flow regulation in hydraulic circuits operating at pressures up to 5,000 psi. Typical install scenarios include mobile hydraulic equipment, industrial machinery, and power unit assemblies where precise flow direction control is required. The 3/4-16 UNF thread ensures compatibility with standard hydraulic fittings used across a wide range of equipment configurations.

Key Features

• Maximum flow rate of 8 GPM
• 3/4-inch inlet with 3/4-16 UNF thread for standard hydraulic fitting compatibility
• Steel body construction for durability under pressure cycling
• Nitrile seals for hydraulic fluid resistance
• Compact at 3.5 inches overall length and 0.7 pounds

Compatibility

Designed as an OEM-style replacement or service valve for hydraulic systems using 3/4-16 UNF threaded connections and operating within an 8 GPM flow rate and 5,000 psi pressure range.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power mechanic. Depressurize and isolate the hydraulic circuit completely before removing or installing any valve components. Ensure thread engagement is correct and use appropriate thread sealant or hydraulic fitting tape as required by system specifications. Verify flow direction arrow or port orientation before final assembly to ensure proper one-way function.
