QZ type electric knife gate valve

此閥是一種新型結構的閥門，他的結構分軟密封和硬密封，軟密封具有活動閥座和可更換的橡膠圈組成，可以很方便的更換用損了的密封圈，而且可以根據客戶需求做成四氟密封，并且能很好的達到密封要求。*彌補了以往四氟難密封和加工不方便的不足。并且支架也是采用鑄造成型結構，使得閥門具有更好的牢固性和使用性。是造紙、工礦、污水、化工、食品領域*產品。該閥門配電動執行器可實現遠程微電腦控制。在電源供應中斷時，也可以通過手動來操作閥門啟閉，從而緊急控制了介質的流向，也避免了事故的發生。也可以使用現場電控箱、遠程PLC電動智能控制等附件來操作和調試的控制。用戶可根據實際需要進行選擇。

Electric knife gate valve that includes soft seal and hard seal is a new structure .Soft seal with activities seat and changeable rubber ring can easily replace damaged seal ring to achieve sealing requirement well , and can be made of PTFE seals according to customer's demands. It compley makes up for past PTFE difficult to seal and processing inconvenient ,and yoke is cast into a model using structure to make valve better robustness and usability. It's suitable for paper making, mining, sewage, chemical industry, food industry .This valve with electric actuator can realize remote microcomputer control. When power is cut off ,it also can be operated by manual to control the flow of media to avoid accidents . You can also use electric control box, remote PLC inligent control ,etc,to operate and debug control. Users can choose according to the their needs.
