氣動薄膜切斷閥(Fa)是采用頂[Ding]導向結構，配用(Yong)多[Duo]彈簧薄膜執[Zhi]行機[Ji] 構。閥體結(Jie)構形式[Shi]有單座(Zuo)、套筒、三[San]通等三種結[Jie]構。具有結構緊 湊、重量輕(Qing)、動作靈敏、流體[Ti]通道呈S流線型(Xing)、壓降損失小、閥(Fa) 容量大、拆裝方便等優點。該閥接收來自調(Diao)節[Jie]儀表的信号，切(Qie)斷、 開啟或改變介質[Zhi]流向，達到對壓力、流量、溫度或液位等工藝參 數自動控制。廣泛應用于環保水處理、石(Shi)油、化工、冶金、電(Dian)力(Li)、 輕工、紡織(Zhi)等各種工業部門的生産[Chan]過程自動控制和遠程[Cheng]控制系統 中(Zhong)。 

The pneumatic diaphragm cut-off valve is subject to a top guide structure with multi spring diaphragm actuator.There are three types of valve body structure：single seat， sleeve and three-way.It has the advantages of compact structure， lightweight， sensi tv e action， S streamlined fluid passage， small pressure drop loss， large valve capacity， convenient disassembly and assembly， etc.The valve receives the signal from the regulating instrument， cuts off， opens or changes the flow direction of the fluid to achieve the automatic control of the process parameters such as pressure， flow， temperature or liquid level.It is widely used in the automatic control and remotecontrol system of production process of environmental protection water treatment， petroleum， chemical industry， metallurgy， electric power， light industry， textile and other industrial sectors.
