The Purpose of Electro Valve Positioner

The electro valve positioner can increase the output power of the regulating valve, reduce the transmission lag 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, ensuring Correct positioning of the regulating valve.

Commonly used actuators are divided into pneumatic actuators and electric actuators, which can be divided into straight travel and angular travel.

Pneumatic control valves used to automatically and manually open and close various valves, wind panels, etc. use compressed air as the power source, cylinders as actuators, and with the help of electrical valve positioners, converters, solenoid valves, retaining valves and other accessories To drive the valve, realize the on-off or proportional adjustment, and receive the control signal of the industrial automation control system to adjust the flow, pressure, temperature and other process parameters of the pipeline medium.

Pneumatic control valve is characterized by simple control, fast response, and intrinsically safe, without additional explosion-proof measures. Features of Pneumatic Motor Pneumatic motor is a prime mover with compressed air as the working medium. It is a power device that uses the expansion of compressed gas to convert pressure energy into mechanical energy.
