The Bosch Rexroth 3WRCBH80VF1800M-1X/ZM-127 (0811402680) is a high-response valve designed for precision control in hydraulic systems. This pilot-operated valve is known for its compact design, making it particularly suitable for space-constrained applications such as those found in the plastic industry at the injection cylinder. The 3WRCBH series valves are built for block installation and feature a 3/2 directional symbol, with a control spool that has an anti-rotation feature and control edges in servo-type quality. Capable of withstanding pressures up to 315 bar, these valves are robust and reliable. They require a pilot line A-X for operation and offer the possibility of dynamic return (B–Z) with sizes 25 and 50. The inclusion of an inductive position transducer allows for position-controlled operation via an external pilot valve and valve electronics, ensuring precise performance. The hysteresis of the Bosch 3WRCBH80VF1800M-1X/ZM-127 is less than 0.1%, indicating extremely accurate control capabilities with minimal variance in response. This precision is further enhanced by the progressive and fine control edge flow characteristics (denoted by "M"), which facilitate smooth and progressive management of fluid flow. These valves are ideal for electro-hydraulic controls within production and test systems, where exacting demands on performance and responsiveness are routine. Their advanced features make them well-suited for applications requiring meticulous modulation of hydraulic fluid flow and pressure, ensuring efficient operation across various demanding scenarios.
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.
