Penumatic Operated Knife Gate Valve

Pneumatic Operated Knife Gate Valve

The pneumatic knife gate valve is to add a pneumatic actuator on the basis of the manual knife gate valve, so as to realize the opening and closing of the valve. It can be divided into two parts, the upper part is the pneumatic actuator, the lower part is the valve body. The pneumatic wafer knife gate valve has the advantages of fast opening and closing speed, reasonable design, compact structure and reliable sealing.

The pneumatic operated knife gate valve can complete the action control and signal output of opening and closing positions and automatic control of continuous action by equipped with solenoid valve, proximity switch and other accessories. Widely used in chemical industry, coal, sugar, sewage, paper and other fields, is an ideal sealing valve. It is especially suitable for regulating and throttling pipe in papermaking industry. It is mainly composed of left and right valve bodies, U-shaped sealing rings, gate plates, steel nuts, valve stems, supports, cylinders and other parts. The opening and closing of valves are completed by cylinder action. The main structural features are: the use of clip structure, small size, light weight. The fully open channel can prevent the medium from depositing in the valve. The newly developed U-shaped sealing ring can ensure the good sealing performance of the valve. The outer sealing of the gate is realized by the elastic sealing strip embedded in the valve body, and can be adjusted with the help of screw and pressing plate. Small flow resistance, convenient installation and maintenance.
