The Bosch Rexroth 4WS2EM16-2X/200B12ET315K8DM (R900940675) is an advanced stage directional servo valve that offers precise control over position, force, pressure, and velocity in hydraulic systems. This valve features a nozzle-flapper plate amplifier for the first stage and can be utilized in either a 4-way or 6-way version depending on the application requirements. It is designed for subplate mounting and conforms to ISO standards with a porting pattern according to DIN form A. With its dry control motor, the 4WS2EM16-2X/200B12ET315K8DM ensures that solenoid gaps remain uncontaminated by hydraulic fluid, thus maintaining the integrity and performance of the system. The valve boasts mechanical feedback or a combination of mechanical and electrical feedback mechanisms, which contribute to its responsive and accurate operation. This model allows for easy maintenance with features such as an exchangeable control sleeve and an externally accessible filter for the first stage. The pilot oil supply can be switched from internal to external without disassembling the valve, demonstrating flexibility in various hydraulic circuit designs. Additionally, whether utilizing external control or opting for integrated electronics (OBE), this servo valve ensures seamless integration into your system as it comes pre-adjusted and tested. With a maximum operating pressure of 315 bar and a maximum flow rate of up to 200 liters per minute, the Bosch Rexroth 4WS2EM16-2X/200B12ET315K8DM servo valve is suitable for high-performance applications that require reliable and precise control over hydraulic functions. Its wear-free control spool return element further emphasizes durability and longevity in demanding operational environments.
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.
