Technical parameters of bidirectional through penetration knife gate valve: The bidirectional through penetration knife gate valve has a cast iron body and an overall structure of knife gate valve, including valve body, gate plate, and U-shaped flexible seal with groove at the bottom of the valve body. When the valve is closed, the bottom edge of the gate comes into contact with the seal, and then the seal is pressed into the groove of the valve body to achieve the sealing of the gate; When the gate is opened, the gate separates from the bottom edge of the seal, and the seal bounces back to the same height as the groove to prevent the accumulation of medium sediment in the groove cavity, without blockage or residue. The pipeline is easy to clean, effectively improving the sealing effect of the knife gate valve and preventing leakage when the valve is closed.
