Electro Pneumatic Valve Positioner

Listing ID #3653995

In addition, the internal position transmitter andor limit switches are easily to be assembled inside of the positioner in order to senses mechanical position change of stem being on the valve or similar device and converses to current signal of DC 4-20mA outputs for computers or Industry Processing Control System. It is flame proof type attached internally.The Linear one is used for linear operation of pneumatic linear valve actuator. The rotary one is used for rotary pneumatic actuator. They control valve stroke accurately, through pressure air, according to input signal of 4-20mA being input from electrical controller control system.
