In this article, we will take a closer look at the features, applications, and advantages of knife gate valves to help you understand how they work and why they are a popular choice for industrial and commercial operations.
How does a knife gate valve work?

A knife gate valve is a type of valve that is used to control the flow of liquids, slurries, and other similar materials in industrial and commercial applications. These valves are known for their durability and reliability and are commonly used as an industrial control valve in a wide range of operations, including mining, power generation, water treatment, and more.

The unique design of a knife gate valve features a stainless steel knife that moves up and down to open or close the flow of the media. Its gate is connected to a hand wheel or an actuator, which is used to open and close the valve. When the valve is open, the gate is raised, allowing the media to flow through, and when the valve is closed, the gate is lowered, blocking the flow.

Additionally, knife gate valves can be actuated by hand wheel, pneumatic, hydraulic, electric, and electro-hydraulic actuators. They can be made for bidirectional flow or unidirectional flow, and a wide range of pressure and temperature ranges.

What are knife gate valves used for?

Knife gate valves are used in a wide range of industrial and commercial applications. Some of the most common applications of knife gate valves include:

HVAC Systems: Used in heating, ventilation and air conditioning systems to control the flow of water and other liquids.
Industrial Processes: Used to control the flow of liquids, gasses, and powders. They are commonly used in the chemical, food and beverage, and pharmaceutical industries, as well as in paper and pulp mills, and cement plants.
Pneumatic Conveying: Controls the flow of materials in pneumatic conveying systems, such as in the mining, fertilizer, and cement industries.
Water and Sewage: Used in water treatment plants and sewage treatment plants to control the flow of water, sewage, and other liquids. Often used in applications where a tight shut-off is required, such as in high-pressure and high-temperature applications.
