Intelligent pneumatic smart valve positioner electro pneumatic positioner

  Advantages: 1.reduce the cost on loop adjustment 2.improve process control 3.auto check and configuration    smart valve positioner   8081 General introduction:     IP8x81 series Intelligent Valve Positioneraccurately controls valve stroke in response to an input signal of 4-20mA from the controller. Built-in micro-processor optimizes the positioner’sperformance and provides unique functions such as Auto-Calibration, and PID Control. Structure: Technical data: How to choose types: Dimension: Working principal:     After the set-point signal(DC4~20mA)input to the circuit board(8), the circuit boar output  a  current to the torque motor(12).The armature become active(13). So, the gap between the baffle(5)and the nozzle(6)increase, and the air in the pilot valve (1)move to right-side, the pressure in OUT1 bigger, diaphragm valve(15)active. The valve’s position feedback to the circuit board by the feedback lever(14), feedback shaft(10) and angle sensor(9)to match the set-point and the position.
