Type YT-1000R Electro-pneumatic valve positioner is used for operation of pneumatic rotary valve actuators by means of electrical controller or control system with an analog output signal of DC 4 to 20 mA or split Ranges.

According to whether the valve positioner has CPU or not, the electro pneumatic positioner can be divided into ordinary
electro valve positioner and intelligent electro valve positioner.
Ordinary electro valve positioners do not have a CPU, so they are not intelligent and cannot process related intelligent
calculations. The intelligent electro valve positioner has a CPU, which can process related intelligent calculations, for
example, it can perform nonlinear compensation of the forward channel, and the fieldbus electric valve positioner can
also be equipped with PID and other functional modules to realize the corresponding calculations.
According to the gain symbol of the valve positioner output and input signal, it is divided into positive acting valve positioner
and reverse acting valve positioner. When the input signal of a positive-acting valve positioner increases, the output signal also
increases, so the gain is positive. When the input signal of the counteracting valve positioner increases, the output signal decreases,
so the gain is negative.
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 valve positioner. The input signal of ordinary valve positioner is analog air pressure or current, voltage
signal, and the input signal of field bus electro valve positioner is the digital signal of field bus.
