Proportional Servo Valve 4WRPEH-2X

Industrial Applications

• The function of proportional servo valve 4WRPEH-2X is that integrated electronic components compare specified control values with actual position values. Structure: Valves mainly include: Direct controlled control valve with control piston and Servo quality sleeve(1) Proportional electromagnet with valve core displacement feedback (2) Integrated digital axis controller with analog and digital sensor interfaces and fieldbus connection (3) Valve function: In the case of control deviation, the coil is activated. Due to changes in the magnetic force of the coil . The contro1 valve core will resist the spring for adjustment. Valve spool stroke and over current cross-sectional area. Directly proportional to the instruction signal. When the preset control value is 0, the electronic element. Adjust the control valve core to resist spring force and move it to the center position. In an inactive state, The spring drives the valve core to put it in a fail safe position. The motion axis controller implements the following control functions Volume flow control Position control Pressure/force control Release position/pressure and position/force control The command value can be input through the analog interface (X1) or Input via bus interface X4 The actual value can be read through the analog interface (X1) or obtained through bus interface X4 Control parameters can be set through the bus Fault diagnosis Integrated electronic components enable control in the following fault conditions, the coil loses power and the control valve core returns to the fail safe position. Power Failure Valve core displacement sensor open circuit fault Communication Failure mA command signal open circuit fault External displacement sensor malfunction External displacement sensor malfunction Package of Proportional Directional Valve 4WRKE-3X
