One way sealed knife gate valve/seat replaceable specification One way sealed knife gate valve adopts a replaceable rubber sealed knife gate structure, and its sealing principle mainly relies on the tight connection between the gate plate and the rubber seal. Its main feature is that the rubber sealing ring is trapped in the valve seat groove and locked by the metal valve seat to prevent the rubber sealing ring from falling off when the valve is opened and closed. If the seal is damaged, you can remove the metal valve seat and replace it with a rubber sealing ring, greatly improving the efficiency of the valve. This type of valve is a cost-effective and high-performance product. This series of knife gate valves can be equipped with pneumatic actuators to meet different industrial and mining requirements.
