With mechanical electro-pneumatic positioner (Special symbol: Z11 (Standard temperature specification), Z12 (High temperature specification))
By directly detecting the stem position and feeding it back to the control pressure of the DC valve, highly accurate flow/pressure control is possible compared to the standard specification that does not have a positioner.
