ZPD1000 type electrical valve positionerDetailed product description：

The ZPD1000 electrical valve positioner is one of the industrial automation instrument varieties and is the main supporting instrument for pneumatic actuators (pneumatic control valves). Used to overcome the unbalanced force caused by the pressure difference of the regulating valve, improve the linearity of the valve position, and thus make the stroke (valve opening) of the regulating valve proportional to the 4-20mA or 0-10mADC current signal output by the regulating instrument, achieving correct positioning. This series of products is a valve control mechanism for electrical signal control and pneumatic control developed by our company based on the original pneumatic valve positioner.
