R4L series intelligent electric valve positioner and pneumatic actuator are used together. By receiving the 4-20ma DC current signal from the control system, the set value of valve position can be obtained. At the same time, the actual value of valve position can be obtained by collecting the position sensor signal. Through the calculation and processing of the control software, the intake and exhaust of pneumatic actuator can be controlled, and the valve position can be driven to the set point.
