Product Overview
The Rexroth STW0195-23/1VS-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. As part of the STW series, this valve utilizes a robust spool-in-housing design that directs pressurized fluid to designated actuator ports based on the position of the control spool. The “24PF6” designation indicates a 24 V DC solenoid-actuated configuration with a specific spool type and spring return arrangement, enabling reliable electrical control of hydraulic cylinders, motors, and rotary actuators. This valve is designed for subplate mounting in accordance with ISO 4401 / DIN 24340 standards, ensuring drop-in compatibility with standard industrial manifolds and power units. Its construction delivers fast response, minimal internal leakage, and long service life, making it a critical control component in high-cycle industrial hydraulic systems.
