The Bosch Rexroth 3WRCBH25V190M-1X/M-127 (0811402509) is a high-response, pilot-operated valve renowned for its servo quality and compact design, making it particularly suitable for use in the plastic industry, especially at the injection cylinder. This model is designed for block installation with a 3/2 directional symbol and features a control spool with an anti-rotation feature that ensures precise operation. The control edges are crafted to servo-type quality, contributing to the valve's high performance. Capable of withstanding pressures up to 315 bar, this valve requires a pilot line A-X for optimal functionality. It also offers the possibility of dynamic return (B–Z) in both size 25 and size 50 variants. Equipped with an inductive position transducer, it allows for position control via an external pilot valve and valve electronics, ensuring accurate and responsive operation. The hysteresis of the 3WRCBH25V190M-1X/M-127 is less than 0.1%, which is negligible and indicates exceptional precision in maintaining set values without significant deviations. Its flow characteristics are progressive with a fine control edge, which facilitates smooth and gradual changes in flow rate. This Bosch valve is ideal for electro-hydraulic controls within production and test systems where precise fluid management is critical. Its advanced features ensure reliable performance in demanding applications where accuracy and response time are paramount.
Valves of type 3WRCBH are pilot-operated high-response valves in servo quality. The design is very compact and is often used in the plastic industry at the injection cylinder.
