Control valve
Thread Content
Our control valves are equipped with valve positioners; what is their function?
A valve positioner is used to automatically control the opening degree of a control valve.
(1) Achieve accurate positioning (2) Improve the dynamic characteristics of the control valve (3) Change the flow characteristics of the control valve (4) Enable step control
The valve potentiometer acts as a transmitter, converting the control output signal from the regulator into a signal that controls the opening degree of the valve； It also serves to enable precise and rapid positioning......
It is intended to better meet the operating conditions by enabling precise adjustment of the valve opening, with the air circuit being controlled via a 4–20mA signal
A positioner is used to adjust the opening degree of the valve. Without a positioner, the control valve cannot be adjusted with precision
