1、氣動隔膜閥門尚可附裝反饋信號、限位器和定位器，以適應自控、程控或調節流量的需要。
2、氣動閥門的反饋信號采用無觸點傳感技術。
3、采用薄膜式氣缸替代活塞式氣缸，排除了活塞環易損漏而導致無法啟閉閥門的弊端。
4、當氣源發生故障時，可操作手輪使閥門開啟。
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.
4.When gas sourse happen to trouble,can operate handwheel to open valve.
