Valves of type 4WS2EM are electrically operated, 2-stage directional servo valves. They are mainly used to control position, force, pressure or velocity. These valves are made of an electro-mechanical converter (torque motor), a hydraulic amplifier (principle: nozzle flapper plate) and a control spool in a sleeve (2nd stage) which is connected with the torque motor via a mechanical feedback.

Rexroth 4WS2EM is an excellent electro-hydraulic servo valve that plays a crucial control and adjustment role in hydraulic equipment. As an electro-hydraulic servo valve, it can convert electrical signals into hydraulic energy and accurately control the flow and pressure in the hydraulic system. By receiving electrical analog signals, it can adjust the output accordingly, thereby achieving precise control of hydraulic equipment. This valve plays a role in the conversion of electro-hydraulic signals and hydraulic amplification in the hydraulic system, enabling the hydraulic system to achieve precise action and adjustment according to control requirements. The characteristics of the 4WS2EM valve are very prominent, such as: 1). High precision control: Rexroth 4WS2EM has extremely high control accuracy, enabling precise control of both flow and pressure adjustments. It can accurately output the corresponding flow and pressure after receiving electrical analog signals, ensuring the accuracy and stability of the hydraulic system. This makes the operation of the hydraulic system more stable and can meet various high-precision control requirements. 2). Quick response: The response speed of this servo valve is very fast, and it can respond quickly whether it is started or stopped, reducing the lag time of the system. This enables the system to respond more quickly to various changes and improves the system's work efficiency. 3). Low friction, low noise, and low leakage: Rexroth 4WS2EM uses high-quality materials and precision manufacturing processes to ensure the low friction and low leakage performance of the valve, reducing the operating noise of the valve in complex working conditions. This not only improves the efficiency of the system, but also extends the service life of the valve. 4). High reliability and stability: This servo valve is designed with full consideration of reliability and stability factors, and can maintain stable performance in various complex hydraulic working environments. It can work reliably in high temperature, low temperature, high pressure, or low pressure environments. 5). Easy to maintain and operate: The structural design of Rexroth 4WS2EM is very user-friendly, making maintenance and operation easier and more convenient. Whether it is installation, debugging, or daily maintenance, it can be completed quickly, reducing user difficulty and maintenance costs.

In summary, Rexroth 4WS2EM has high application value in the field of hydraulic control due to its high precision control, fast response, low friction, low leakage, high reliability and stability, and easy maintenance and operation. These advantages make Rexroth 4WS2EM have broad application prospects in hydraulic control systems. In addition, its built-in amplifier has been adjusted and tested, which greatly reduces the difficulty of user use and improves the reliability of the system. Moreover, the Rexroth 4WS2EM valve has excellent reliability and stability, which can maintain high-precision control for a long time, reduce failure rates, and extend service life. Rexroth 4WS2EM requires high cleanliness of the oil and requires a high-precision filtration system, otherwise it may affect the performance and lifespan of the valve. The requirement for power supply is also high, requiring a stable power supply, otherwise it may affect its performance.

Rexroth 4WS2EM(4WS2EM6, 4WSE2EM6, 4WS2EM10, 4WS2ED10, 4WSE2EM10, 4WSE2ED10, 4WSE3E16, 4WSE3E25, 4WSE3E32) is mainly used in hydraulic equipment that requires high-precision control, such as injection molding machines, die-casting machines, rubber machines, shoe machines, metallurgical equipment, mining machinery, engineering machinery, shipbuilding, aviation and other hydraulic systems.
