Product Overview
The Rexroth HD-2-X (R431002833) is a pneumatically actuated directional control valve engineered for precise switching and routing of compressed air in industrial process circuits. As part of Rexroth’s HD series, this valve utilizes a balanced spool design that shifts under pneumatic pilot signal to direct airflow between ports with minimal pressure drop and fast response. Its robust housing and precision-machined spool deliver reliable directional control in automated pneumatic systems, serving as a critical interface component for actuator sequencing, cylinder extension/retraction, and process line switching. The HD-2-X is designed as a direct-fit replacement for OEM installations, ensuring dimensional and functional compatibility with existing Rexroth pneumatic valve manifolds and subplates.
