四柱式气动刀闸阀

dark rok pneumatic knife gate valve

四柱式气动刀闸阀是一种新型结构的阀门，他的结构分软密封和硬密封，软密封具有活动阀座和可更换的橡胶圈组成，可以很方便的更换用损了的密封圈，而且可以根据客户需求做成四氟密封，并且能很好的达到密封要求。*弥补了以往四氟难密封和加工不方便的不足。并且支架也是采用铸造成型结构，使得阀门具有更好的牢固性和使用性。是造纸、工矿、污水、化工、食品领域*产品。

Four-column-type pneumatic knife gate valve that includes soft seal and hard seal is a new structure .Soft seal with activities seat and changeable rubber ring composition can easily replace damage seal ring to achieve sealing requirement well , and can be made of PTFE seals according to customer's demands, and can achieve good sealing requirements. It compley makes up for past PTFE difficult to seal and processing inconvenient ,and yoke is casted into a model using structure to valve with better robustness and usability. It's suitable for paper making, mining, sewage, chemical industry, food industry .
