The Bosch Rexroth 3WRCBH32VF380M-1X/M-127 (0811402609) is a high-response valve designed for precise control in hydraulic systems. The valve features a block installation design with a 3/2 directional symbol, ensuring efficient direction of flow from P→A / A→T. It is equipped with a control spool that has an anti-rotation feature and control edges of servo-type quality, offering exceptional precision in operation. Capable of withstanding pressures up to 315 bar, this valve is suitable for high-pressure applications. The requirement for a pilot line A-X is standard for its operation, ensuring stability and responsiveness. Additionally, the valve allows for dynamic return (B–Z), expanding its functionality in various system configurations. The inclusion of an inductive position transducer enables position-controlled operations via an external pilot valve and corresponding valve electronics, which enhances the accuracy and reliability of the system. This advanced feature contributes to the valve's extremely low hysteresis of less than 0.1%, which is practically immeasurable, thereby ensuring smooth and precise control. With progressive and fine control edge flow characteristics (M), the Bosch 3WRCBH32VF380M-1X/M-127 valve excels at managing fluid dynamics within electro-hydraulic controls used in both production and test systems. Its compact design makes it particularly well-suited for applications within the plastic industry, such as at the injection cylinder where space may be limited and precision is critical.
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.
