What are the media used for knife gate valves?

What are the media used for knife gate valves? Knife gate valves, with their unique design and performance, are widely used in many fields and are suitable for a variety of different media.

1. Pulp. In the papermaking process, the transportation and control of pulp require stable and reliable valves. The knife-shaped oblique cut design of the knife gate valve enables it to effectively cut off the pulp medium and prevent the valve from being blocked when it is closed. Coal ash is also a medium suitable for knife gate valves. For example, in the process of handling fly ash in thermal power plants, knife gate valves can ensure the smooth flow of coal ash transportation lines.

2. Chemical raw materials. Chemical production involves a variety of corrosive raw materials. Knife gate valves made of some special materials can resist these corrosive media and ensure production safety. The treatment and discharge of sewage are also inseparable from knife gate valves, which can adapt to the characteristics of more impurities in sewage and achieve stable switching operations.

3. Food industry. In the food processing process, for some fluid or granular food raw materials, knife gate valves can meet their regulation and interception needs, and their reliable sealing characteristics can ensure the hygiene and safety of food.

In addition, in the fields of mining, the pneumatic knife gate valve can cope with the harsh dust working conditions by using high-strength and wear-resistant alloy material valve stem, valve plate and multi-layer high-performance sealing structure to transport dust and tiny ore particles. The pneumatic ceramic knife gate valve is suitable for solid, liquid-solid, gas-solid two-phase medium transportation systems such as high-hardness particles, soft particles but corrosive media, such as ash, mud, coal slurry, ore slurry, etc.
