Classification of valve positioners:
It is divided into pneumatic valve positioner, electro pneumatic valve positioner and intelligent valve positioner according to the input signal.
According to the direction of action, it can be divided into one-way valve positioner and two-way valve positioner.
According to the gain sign of the valve positioner output and input signal, it is divided into positive acting valve positioner and reverse acting valve positioner.
According to whether the input signal of the valve positioner is analog signal or digital signal, it can be divided into ordinary valve positioner and fieldbus electro pneumatic valve positioner.
According to whether the valve positioner has CPU or not, it can be divided into ordinary electro pneumatic valve positioner and intelligent electro pneumatic valve positioner.
Smart valve positioner
The intelligent valve positioner is an intelligent process control instrument based on microprocessor technology and adopts digital technology for data processing, decision generation and two-way communication. It does not require manual adjustment and can automatically detect the zero point, full range, and friction of the regulating valve. Coefficient, automatically set control parameters.
A valve positioner that does not require manual adjustment, can automatically detect the zero point, full stroke, and friction coefficient of the regulating valve, and automatically set the control parameters.
