 ◆ Overview: 

 Electrical valve positioner generally refers to the pneumatic valve positioner. 

 The pneumatic valve positioner is one of the important accessories and accessories of the pneumatic regulating valve. It plays the role of valve positioning. 

 ◆ Main functions: 

 The pneumatic valve positioner and the pneumatic actuator together form an automatic control unit and various regulating valves. After debugging and installation, they are combined into a pneumatic regulating valve. 

 It is used in various fields of industrial automation process control. 

 ◆ Structural principle: 

 The pneumatic valve positioner receives weak electrical signals such as 4 to 20mA from the controller or control system, and transmits air signals to the pneumatic actuator to control the valve position. 

 It is used with a pneumatic regulating valve to form a closed-loop control circuit. Convert the DC current signal given by the control system into the air signal of the driving control valve and control the action of the control valve. At the same time, feedback is made according to the opening of the regulating valve, so that the valve position can be correctly positioned according to the control signal output by the system. 

 ◆ Supporting use: 

 It can be used for single-acting (spring reset) and double-acting pneumatic actuators.

Each process, each facility, and each environmental constraint has its own special requirements. As a result, Kinko offers a comprehensive range of products that include different performance levels, pressures, functions and materials.
