ZPQ pneumatic positioner industrial automation pneumatic actuator supporting the main instrument used to improve the linearity of valve position to overcome friction and to eliminate the influence of the stem valve of the unbalanced force, so as to ensure that the valve position by adjusting instrument to pressure signals into 20 ~ 100KPa than the column relations and achieve proper positioning. 

  This series of products with pneumatic diaphragm actuator can also be equipped with gas piston actuator; with straight trip to the control valve, control valve stroke can also supporting role. Therefore, it is widely used in petroleum, chemical, metallurgy, power, textile, paper and other industrial automation, industrial automation instrument is an indispensable product.
