The Bosch Rexroth 4WS2EM16-2X/150B12ET315K8DM (R900931560) is an advanced servo valve designed for precision control of position, force, pressure, or velocity in hydraulic systems. This electrically operated stage directional servo valve comes in a 4-way version and is equipped with either integrated or external control electronics. It features mechanical feedback or a combination of mechanical and electrical feedback for accurate system responses. The valve's porting pattern adheres to the DIN form A standard, ensuring compatibility with a wide range of mounting configurations. The 4WS2EM16-2X/150B12ET315K8DM boasts a nozzle-flapper plate amplifier at its first stage and is suitable for subplate mounting due to its ISO-compliant porting pattern. Its dry control motor design ensures that the solenoid gaps remain free from hydraulic fluid contamination, enhancing the longevity and reliability of the valve. Additionally, this model can function as a 3-way version if required. One of the key features of this Bosch Rexroth servo valve is its wear-free control spool return element, which contributes to its durability. Users have the flexibility to choose between external control electronics or take advantage of the integrated OBE (On-Board Electronics). Both the valve and its electronics are precisely adjusted and tested to ensure optimal performance. Maintenance and customization are made simple with this servo valve. The pilot oil supply can be switched from internal to external without disassembling the entire valve, and the control sleeve is exchangeable. Furthermore, there is an easily accessible filter for the first stage that can be serviced from outside. In terms of specifications, this servo valve has a size component series X, can handle a maximum operating pressure of up to 315 bar, and allows for a maximum flow rate of up to 150 liters per minute. These features make it an excellent choice for demanding applications requiring precise hydraulic control.
