The Bosch Rexroth 3WRCBH50VF750M-1X/ZM-127 (0811402637) is a highly sophisticated pilot-operated high-response valve designed for precision applications. This compact valve is particularly suitable for the plastics industry, where it is commonly utilized at the injection cylinder to ensure meticulous control of the molding process. The 3WRCBH series valves are known for their servo quality and are engineered for block installation with a 3/2 directional symbol. Featuring a control spool with an anti-rotation feature and servo-type quality control edges, this valve assures users of its reliability and performance. It can handle pressures up to 315 bar, making it robust enough for demanding applications. The necessity of a pilot line A-X is standard with this model to facilitate proper functioning. The dynamic return capability is available with sizes 25 and 50, enhancing the valve's flexibility in various system configurations. An inductive position transducer comes integrated into the valve, which allows for position-controlled operation in conjunction with an external pilot valve and corresponding valve electronics. One of the standout features of this model is its hysteresis, which is less than 0.1%, indicating extremely precise control that is virtually immeasurable. This level of precision ensures that flow characteristics are maintained consistently throughout operations. The flow characteristics of the Bosch 3WRCBH50VF750M-1X/ZM-127 are progressive with a fine control edge, making it ideal for electro-hydraulic controls within both production and test systems where accuracy and responsiveness are critical. The combination of advanced design features and robust construction makes this valve an essential component for specialized industrial applications requiring meticulous hydraulic control.
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.
