The valve positioner is divided into pneumatic valve positioner, electro pneumatic valve positioner and smart valve positioner according to the
structure. It is the main accessory of the control valve. It is usually used in
conjunction with the pneumatic control valve. It receives the output signal of
the regulator and then uses its The output signal is used to control the
pneumatic control valve. When the control valve is actuated, the displacement
of the valve stem is fed back to the valve positioner through the mechanical
device, and the valve position status is transmitted to the upper system
through the electric signal.Valve positioners can be divided into pneumatic
valve positioners, electro-pneumatic valve positioners, and intelligent valve
positioners according to their structure and working principle. The valve
positioner can increase the output power of the regulating valve, reduce the
lag in the transmission of the regulating signal, accelerate the movement speed
of the valve stem, improve the linearity of the valve, overcome the friction of
the valve stem and eliminate the influence of unbalanced force. So as to ensure
the correct positioning of the regulating valve.
