西门子系列智能是拨动阀门定位器用于气动直行程或角行程机构的控制。低耗气量低耗气量带来的低成本运行，另一个显著的特点是极低的耗气量。传统的阀门定位器在工作中会有很多仪表空气的排放可泄漏，造成仪表空气的较大需求，产生高的运行成本。由于新的压电阀的技术，阀门不动作是不会有任何仪表空气排放，它又在最需要的时间一阀门动作的时候用气。

62 Simens 6DR5220-OEN01-OAAD locator is used for controlof pneumatic straight travel(angle travel). Low air consumption can save cost with very low air consumption. Traditional valve locator willhave a lot of air release, which causes high demand of air and increasecost a lot. Because of technologies of new piezoelectricity valves, therewill be no air consumption when valves do not work. Only when valvesmove, air will be in need.
