    Pneumatic Knife Gate Valve Details

    Knife gate valves are generally used for the circulation of media such as paper pulp, coal ash, chemical materials, sewage, and foodstuffs. ATO knife gate valve has the remarkable advantages of light switch, good sealing, good elastic memory, and long service life. It can be widely used in water, sewage, construction, petroleum, chemical, food, medicine, light textile, electric power, ship metallurgy, energy system and another body pipeline as a regulating and intercepting device.Knife gate valve application

    Tips: What is pneumatic knife gate valve?

    A pneumatic knife gate valve is a type of gate valve that uses compressed air to actuate the valve's opening and closing mechanism. It is typically used in industrial applications, such as fluid or material transfer in pipelines, to control the flow of liquids or solids. The valve's design features a gate or "knife" that moves up and down to open or close the flow path. The pneumatic actuator provides fast, reliable, and precise control, making it a popular choice in process control applications.
