Product introduction

The four-column knife gate valve is a new type of valve. Its structure is divided into soft seal and hard seal. The soft seal has a movable valve seat and a replaceable rubber ring. It can be easily replaced with a damaged seal ring. According to the customer's requirements, it is made of PTFE seal and can meet the sealing requirements very well. It completely compensates for the inadequacy of PTFE's difficult sealing and inconvenient processing. And the bracket is also cast-formed structure, which makes the valve have better firmness and usability. It is the first choice in paper, industrial, mining, sewage, chemical and food fields.
