The Bosch Rexroth 4WS2EM16-2X/200B12ET315K8EV (R900960575) is an advanced stage directional servo valve designed for precise control in hydraulic systems. This model features integrated or external control electronics, which allow for the management of position, force, pressure, or velocity. Its construction includes a mechanical feedback system, or a combination of mechanical and electrical feedback, to ensure accurate system responses and adjustments. The valve's porting pattern adheres to ISO standards for subplate mounting, ensuring compatibility and ease of installation in various applications. One of the key benefits of this servo valve is its dry control motor design. This feature prevents contamination of the solenoid gaps by hydraulic fluid, enhancing the valve's reliability and longevity. Additionally, the 4WS2EM16-2X/200B12ET315K8EV can function as a way version valve if required. It includes a wear-free control spool return element that contributes to its durability and consistent performance over time. The flexibility of the pilot oil supply is another notable feature; it can be switched from internal to external without disassembling the valve, offering convenient maintenance and adaptability. For ease of serviceability, the control sleeve is exchangeable and there is an externally accessible filter for the first stage. Both the valve and its integrated control electronics are carefully adjusted and tested before deployment to ensure optimal performance upon installation. Overall, this Bosch Rexroth servo valve stands out for its precision engineering, versatility in controlling various parameters within hydraulic systems, and thoughtful design that emphasizes maintainability and operational efficiency.
Valves of type 4WS(E)2E... re electrically operated, 2-stage directional servo valves in 4-way version with integrated or external control electronics. They moreover have a mechanical or mechanical and electrical feedback. The porting pattern is designed according to DIN 24 340 form A16. The valves are mainly used to control position, force and velocity.
