Pneumatic Knife Gate Valve

A pneumatic knife gate valve is a valve controlled by a pneumatic device, typically used to shut off the flow of fluids. Its design generally consists of a blade (also known as a knife) and a valve body. The blade is usually flat and positioned within the fluid passage. Through the operation of a pneumatic device, the blade can be moved along the direction of fluid flow, allowing for the opening or closing of the fluid passage.

Key features include:Cut-off function: Pneumatic knife gate valves are designed to quickly and thoroughly cut off the flow of fluids. When the blade is closed, fluid cannot pass through, achieving an effective shut-off.

Simple structure: The structure of a knife gate valve is relatively simple, typically composed of a valve body and a blade, reducing the number of components. This simplicity makes maintenance and repairs relatively straightforward.

High flow capacity: Due to the blade design, pneumatic knife gate valves provide a relatively large passage when open, reducing resistance to fluid flow and making them suitable for high-flow conditions.

Suitability for contaminated media: The simple structure of a knife gate valve makes it less prone to clogging by particles or contaminants in the media, making it suitable for media with impurities or particulate matter.

Pneumatic control: Knife gate valves are often controlled using pneumatic devices, allowing for remote operation and automation through pneumatic systems.

Pneumatic knife gate valves are widely used in industrial applications where there is a need to quickly shut off fluid flow, such as in emergency situations or in processes that require frequent fluid cut-off.
