The square sewage pneumatic knife gate valve is sealed between the gate and the sealing surface, mainly with metal sealing. This type of valve is best installed horizontally.
The bidirectional self sealing pneumatic knife gate valve uses two rubber valve seats to clamp and press the gate to achieve a sealing effect. When the gate is fully opened
No groove design, dual bidirectional sealing structure, adopting a split structure including valve body, gate plate, and U-shaped sealing strip.
