4WS2EM10-52/60B11T315K31CV-114 is a high-performance electro-hydraulic servo directional valve produced by Bosch Rexroth in Germany. This model usually corresponds to material number R900772317.
The following are the core parameters and technical features of the product:
1. Basic specifications
Brand: REXROTH (Rexroth)
Series: 4WS2EM10 (diameter 10, component series 5x)
Type: Four way servo directional valve with electrical valve core position feedback and integrated control electronic components
Rated flow rate: approximately 60 l/min (at a pressure drop of Δ p=10 MPa)
Maximum working pressure: 315 bar
Installation Connection: Compliant with ISO 4401-05-05-05-00 (Base Plate Installation)
2. Model code analysis
4WS2EM10: Four way servo valve, diameter 10, with integrated electronic amplifier.
52: Component series 52 (installation and connection dimensions remain unchanged, internal structure may be optimized).
60: The rated flow rate is 60 l/min.
B11: Valve core function symbol (usually designed as a symmetrical valve port, please refer to the sample diagram for details, generally used for bidirectional control).
T315: The sealing material is suitable for a maximum oil temperature of 80 ° C and a pressure rating of 315 bar.
K31: Electrical connection method, usually referring to a 7-pin plug (6+PE) that complies with DIN EN 175201-804 standard.
CV: Refers to a closed-loop control with electrical position feedback device, which has closed-loop control function and higher accuracy than the pure mechanical feedback version.
-114: Specific variant code, usually involving voltage level, zero adjustment, or special certification requirements (such as explosion-proof, etc., which need to be confirmed in conjunction with the order data sheet, commonly ± 15 V DC power supply or specific amplifier matching).
3. Main features and applications
High precision control: Due to the integration of inductive displacement sensors and built-in electronic amplifiers, electrical closed-loop control of valve core position is achieved, with extremely high repeatability and linearity.
Fast dynamic response: suitable for electro-hydraulic servo systems that require fast response and high bandwidth.
Fault safety: Even if the electrical feedback fails, the mechanical feedback spring can still ensure that the valve core returns to the zero position (center position), ensuring system safety.
Typical applications: Industrial hydraulic systems that require extremely high precision in position and speed control, such as injection molding machines, testing machines, machine tool spindle drives, and metallurgical equipment.
