◆ Overview:

Electrical valve positioners generally refer to pneumatic valve positioners.

The pneumatic valve positioner is one of the important accessories and parts of the pneumatic control valve. It serves to position the valve.

◆ Main functions:

The pneumatic valve positioner, together with the pneumatic actuator, forms the automatic control unit and is connected to various control valves. After commissioning and installation, they are combined into a pneumatic control valve.

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

◆ Structural principle:

A pneumatic valve positioner is a device that receives weak electrical signals such as 4 ~ 20mA from the controller or control system and sends air signals to the pneumatic actuator to control the valve position.

It is used in conjunction with pneumatic control valves to form a closed-loop control circuit. Convert the DC current signal provided by the control system into an air signal to drive the regulating valve and control the operation of the regulating valve. At the same time, feedback is provided based on the opening degree of the regulating valve to ensure that the valve position can be accurately positioned according to the control signal output by the system.

◆ Compatible use:

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