action principle
TS900 receives the current signal of the control room (4-20mA), the displacement change of the valve stem drives the resistance change of the potentiometer, and the central processing unit (CPU) on the circuit board The two signals are compared and the control instructions are transmitted to the torque motor (IP converter), which converts the instructions into a pressure signal to adjust the output pressure of outlet 1 and outlet 2 of the pilot valve to control the opening of the valve.
Note: before installing the product, please confirm whether the valve and actuator meet the site requirements. If the installation status is not correct, the adjustment performance of the product will be reduced.
