Product Overview
The Rexroth STW0195-23/1V5-24PF6 (Material Number: R901105881) is a high-performance directional spool valve engineered by Bosch Rexroth for precise control of hydraulic fluid flow direction, distribution, and pressure in demanding industrial circuits. Utilizing a robust spool-and-sleeve working principle, this valve directs pressurized fluid to specific actuator ports through axial displacement of a precision-ground control spool, enabling forward, reverse, and neutral operating states. As a direct-operated directional control valve, it serves as a critical control element in hydraulic power units, manifolds, and integrated circuit blocks, delivering reliable switching logic for single and double-acting cylinders, motors, and rotary actuators across heavy-duty machinery.
