○ The bottom of the gate is designed with a diagonal angle
○ Wedges on both sides of the valve body
○ The above two characteristics ensure that the gate plate plays a limiting role when it is closed, effectively increasing the service life of the sealing ring
○ Two type new bracket, increasing the strength of the bracket
○ The square sewage pneumatic knife gate valve is mainly sealed with metal between the gate and the sealing surface. This type of valve is best installed horizontally. It has the advantages of no material jamming, sturdy structure, and long service life
○ Bottom discharge control valve for square channels or boxes in sewage treatment plants
○ Square pipeline high concentration slurry discharge point for papermaking white water recovery system
○ Remote pneumatic opening and closing device for square sewage outlet of chemical plant sedimentation tank
○ Regular dredging and automatic discharge valve for square chutes in mining tailings treatment
○ Bottom discharge control of square conveyor trough for starch or residue in the food industry
Bidirectional sealed knife gate valve, with no groove design, adopts a split structure, and an improved polyurethane lined valve seat sealing ring fully protects the valve body from medium erosion
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 movable structure of replaceable rubber sealing ring is mainly achieved through the close contact between the gate and rubber sealing ring to achieve sealing effect.
