Rexroth servo valve is one of the main products of Bosch Rexroth, a common hydraulic control component widely used in various industrial equipment. The following is its related introduction:

Working principle: It belongs to a two-stage valve. The first stage is a nozzle baffle plate, which is controlled by a control signal to control its outlet pressure. The second stage is a slide valve type, which controls the pressure from the control stage to the brake cylinder. When there is no signal, due to the effect of the oil pressure at the outlet of the pressure nozzle, the servo valve baffle is pressed against the return oil nozzle. At this time, the oil pressure at the pressure port acts on the spool valve core, directly connecting the brake port with the metering oil port. The brake port pressure is equal to the metering oil pressure controlled by the pilot. When the wheel angular velocity detects a deviation between the sliding speed and the reference sliding speed, the torque motor receives a deviation electrical signal. At this time, the torque motor drives the gear plate to deflect towards the pressure nozzle, causing the oil pressure acting on the upper end of the spool to decrease. Under the action of the oil pressure at the lower end of the spool, the spool moves upward, closing the metering pressure oil port. This will cause the control port pressure to decrease. When the control port pressure drops to a certain value, there is corresponding braking pressure. A typical servo valve consists of a permanent magnet torque motor, nozzle, baffle, valve core, valve sleeve, and control chamber.

Features:

Adopting digital control technology: with efficient and stable performance characteristics, high control accuracy, fast response speed, long service life, and good adaptability, it can be applied to various industrial environments and needs.

Excellent electromagnetic coil design and high-strength material manufacturing process have improved its performance indicators such as high temperature resistance, low temperature resistance, corrosion resistance, and wear resistance.

Application areas: Widely used in multiple industries such as machine tools, metallurgy, plastics, papermaking, petrochemicals, and automobiles. For example, in the machine tool industry, precise control of hydraulic systems can achieve technical requirements such as high-speed cutting, precision machining, and complex contour cutting during the machining process, greatly improving machine tool production efficiency and product quality; In the metallurgical industry, it is mainly used in cooling equipment, steel processing, slab rolling and other links, which can achieve stable control of key indicators such as steel temperature, oxygen content, and molten iron quality, and improve the efficiency and quality of steel production; In the plastic processing industry, it is applied to equipment such as injection molding machines, extruders, blow molding machines, etc. By accurately controlling the hydraulic systems in these equipment, precise processing and molding of plastic materials can be achieved, improving product quality and production efficiency.
