Most of the current valves are intelligent integrated, automated control of the valve through circuitry. The circuit system implements control, feedback and adjustment of the valve opening degree, and is accurately correct, its focus is precise feedback from the valve position.
In order to enable the electric actuator
to detect and feedback to the valve in the running process to ensure that the opening degree of the valve is important at the designated position, the position sensor is very important. Briefly describes the advantages and disadvantages of several common position electric actuators
in the market in different markets.
The electric actuator is required to perform real-time detection during the operation of the valve to ensure that the opening of the valve is in the designated position, thereby achieving normal operation of the entire fluid engineering system. Therefore, the position sensor in the electric actuator (also called the valve position detection device) is very important.
