Description
Knife gate valve is composed by a replaceable rubber seal knife gate structure, and the sealing is produced with the connection between gate and rubber seals. The main feature is that the rubber sealing ring is settled in the valve seat and is locked by metal seat, which will prevent rubber seal from detaching when opening and closing the valve. If the seal is broken, you can remove the metal seat and replace the rubber seal, which will greatly improve valve’ working efficiency. This valve is a high-performance product. The knife gate valve can be equipped with pneumatic actuators, in order to meet the requirements of different industrial and mining use.
