The Bosch Rexroth 4WSE2EM16-2X/200B8ET210K9EV (R900246719) is a high-performance directional servo valve designed for precise control in hydraulic systems. This advanced valve is capable of managing position, force, pressure, or velocity with exceptional accuracy and responsiveness. It features a two-stage operation with a nozzle-flapper plate amplifier in the first stage and a robust design that includes mechanical or mechanical and electrical feedback options to ensure optimal performance. Its construction allows for subplate mounting with a porting pattern that conforms to ISO standards, ensuring compatibility and ease of integration into various hydraulic circuits. The dry control motor design ensures that the solenoid gaps remain uncontaminated by hydraulic fluid, enhancing the valve's reliability and service life. The 4WSE2EM16-2X/200B8ET210K9EV can function as both a 4-way and a 3-way valve, providing flexibility for different application requirements. The wear-free control spool return element contributes to the valve's longevity, while the option to control externally or with integrated electronics (OBE) adds versatility. This servo valve comes pre-adjusted and tested alongside its integrated control electronics for seamless installation and immediate operation. Additionally, the pilot oil supply can be switched from internal to external without disassembling the valve, simplifying maintenance procedures. A notable feature of this Bosch Rexroth servo valve is its exchangeable control sleeve and an externally accessible filter for the first stage, which facilitates easy servicing and minimizes downtime. The combination of these features makes the 4WSE2EM16-2X/200B8ET210K9EV an ideal choice for applications requiring precise hydraulic control with high reliability and maintainability.
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.
