Electro-pneumatic valve positioner is used to adjust and control pneumatic actuator. The pneumatic actuator finally drives the valve to the set point sent by control system. The valve positioner continues detecting the current position of valve and compares to the set point. The input to an electro-pneumatic valve positioner is electrical signal. The output to the pneumatic actuator is increase or decrease of compressed air.

The features are:

♦  Ultra low air consumption at 36L/h.
♦  Fail freeze function without external solenoid valve.
♦  Attachment to linear or rotary actuators in accordance with IEC/VDE standard.
♦  Easy commissioning and operation.
♦  With lightening protection.
