○ Applicable media: Suitable for mud, urban sewage treatment, sugar factories, powders, papermaking, pharmaceuticals, chemicals, food and other fields
○ Integrated valve body
○ Bilateral PU protective cover
○ Two type new bracket, increasing the strength of the bracket
○ Valve body with flow guide design to prevent fluid from being trapped in the valve chamber
○ No groove design, bidirectional sealing structure, adopting a split structure including valve body, gate plate, and U-shaped sealing strip. The left and right sides of the valve body and the bottom of the middle chamber are equipped with grooves and elastic U-shaped sealing strips.
○ When closed, the gate moves downwards, and the bottom edge of the gate contacts the sealing strip, compressing the sealing strip into the groove to achieve sealing between the valve body and the gate.
○ When the gate valve is opened, it moves upward and the bottom edge of the gate valve separates from the sealing strip. The sealing strip bounces up and the groove is flat, which can prevent the medium sediment from accumulating in the groove of the valve body during the use of the knife gate valve.
○ Not easy to block, no residue, easy to clean pipeline, thus effectively improving the sealing effect of knife gate valve and preventing leakage when the valve is closed.
○ Automatic truncation control of pneumatic ash conveying pipelines in power plants under high wear conditions
○ Cut off valve for solid particle slurry in mining tailings conveying system
○ Remote wear-resistant switch device for raw material or clinker powder pipeline in cement plant
○ Application of wear-resistant sealing gate valve in the coal powder injection system of blast furnaces in the metallurgical industry
○ Control points for erosion resistant pneumatic partitions in papermaking and pulp black liquor sand containing pipelines
The circular 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.
The structural design of replaceable rubber sealing rings mainly relies on the close contact between the gate and the rubber sealing ring to achieve a sealing effect.
Pneumatic penetrating plug valve is a type of valve in which the gate and valve seat are always in close contact and sealed. Its principle is that the gate has a circular opening of the same diameter
