JQB Series unidirectional seal knife valve/light seat replaceable

Product Description: JQB Series Knife gate valve is with replaceable rubber seal knife gate structure, its sealing principle is mainly by the close connection between the gate and rubber seals. Its main character is that the rubber sealing ring is set in seat groove and is locked by metal seat, which will prevent rubber seal off when opening and closing the valve. If the seal is broken, you can remove the metal sear and replace the rubber seal, which will greatly improve the valve’s working efficiency. This valve is a cost-effective, high-performance product. The series of knife gate valve can be equipped with pneumatic actuators, in order to meet the requirements of different industrial and mining use.
