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 cost-effective, high-performance products.
The series of knife gate valve can be equipped with pneumatic actuators, in order to meet the requirements of different industrial and mining use.
