○ Applicable media: Suitable for mud, urban sewage treatment, sugar factories, powders, papermaking, pharmaceuticals, chemicals, food and other fields
○ 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
○ Valve body with flow guide design to prevent fluid from being trapped in the valve chamber
○ PTFE limit block ensures that the gate does not come into contact with the valve body, extending the service life of the gate
○ No groove design, bidirectional sealing structure, adopting an integral 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 shut-off valve for high concentration pulp conveying pipeline in papermaking and pulp making process
○ Remote control point for opening and closing the slurry pipeline at the outlet of the slurry mill or dewatering machine
○ Pneumatic sewage cut-off device for the discharge pipe of black liquor extraction and washing system
○ Rapid sealing and emptying operation of the discharge port at the bottom of the slurry storage tank
○ Corrosion resistant pneumatic gate valve for corrosive slurry pipeline in pulp and bleaching section
Bidirectional self sealing manual knife gate valve uses two rubber valve seats to clamp and press the gate to achieve a sealing effect.
No grooves, rubber lining, bidirectional sealing design, valve body adopts a split structure including valve body, gate plate, and U-shaped sealing strip.
No groove design, dual bidirectional sealing structure, adopting a split structure including valve body, gate plate, and U-shaped sealing strip.
