1、气动隔膜阀门尚可附装反馈信号、限位器和定位器,以适应自控、程控或调节流量的需要。 2、气动阀门的反馈信号采用无触点传感技术。 3、采用薄膜式气缸替代活塞式气缸,排除了活塞环易损漏而导致无法启闭阀门的弊端。 4、当气源发生故障时,可操作手轮使阀门开启。 Note:1.Pneumatic diaphragm valve also can be installed feedback signal,limited machine or localizer in order to adapt to the requirements of automatic,programed control or flow rate adjustment. 2.The feedback signal of pneumatic valve is adopted the sense technology of non-contact. 3.Adopt film cylinder in place of piston cylinder,which remove the abuse that piston ring is easily damaged and lead to not open or close valve.
