Allen-Bradley WS22GNRSADB-10-4 Directional Control Valve

Description:

The WS22GNRSADB-10-4 Valve is used in industrial hydraulic systems as a high-pressure screw-in cartridge directional control valve for precise fluid shutoff and load holding applications. It is part of the WS22 series hydraulic seat-valve family, designed for leak-tight 2-way/2-position control in demanding hydraulic circuits where safe isolation of pressure lines is required. Commonly installed in hydraulic power units, clamping systems, industrial presses, and automation machinery where secure pressure retention and fast switching are critical. Maintenance teams, OEM manufacturers, and system integrators use this part for replacement of failed cartridge valves, hydraulic system repair, and restoration of pressure control functionality.

Applications:

The WS22GNRSADB-10-4 is used in hydraulic control systems to manage on/off flow control and maintain clamping or holding pressure in industrial machinery. It is commonly applied in hydraulic presses, injection molding machines, machine tool clamping systems, and automated production equipment where zero-leak shutoff and high-pressure reliability are required.
