The Bosch Rexroth 4WS2EM16-2X/200B12ET210K8AV (R901046868) is an advanced stage directional servo valve designed for high precision control of position, force, pressure, or velocity in hydraulic systems. This valve features both mechanical and optional mechanical and electrical feedback mechanisms, ensuring accurate and responsive operation. It is equipped with a first-stage nozzle-flapper plate amplifier and is configured for subplate mounting with a porting pattern that conforms to ISO standards, specifically DIN form A. The 4WS2EM16-2X/200B12ET210K8AV valve boasts a dry control motor which prevents contamination of the solenoid gaps by hydraulic fluid, thus maintaining the purity of the system. Its design allows it to function effectively as a way version valve if required. Noteworthy is the wear-free control spool return element that contributes to the valve's durability and longevity. This servo valve can be operated with external control electronics or with integrated On-Board Electronics (OBE). The integration ensures that both the valve and its control electronics are finely tuned and tested together for optimal performance. Additionally, users have the flexibility to switch the pilot oil supply from internal to external without disassembling the valve, which enhances maintenance convenience. Furthermore, the control sleeve of this servo valve is exchangeable, which adds to its serviceability. The filter for the first stage is easily accessible from outside, simplifying any necessary cleaning or replacement tasks. Overall, this Bosch Rexroth servo valve represents a reliable solution for precise hydraulic control in various applications where accuracy and adaptability are paramount.
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.
