Valve positioners are used to control and adjust pneumatic control valves. The main features of valve positioners include:
Valve positioners are an essential component for controlling pneumatic control valves. The working principle of valve positioners is based on the conversion of electrical signals into pressure signals. This pressure is used to control the position of the valve stem, which adjusts the flow rate of the fluid.
The core mechanism of valve positioners includes the nozzle flapper and the film chamber. These components sense the pressure and adjust the position of the valve stem, which achieves the purpose of precise control.
