Products Details

Pneumatic dust butterfly valve is a valve used to control the flow of dust or other granular media in the pipeline. It has the characteristics of simple structure, small size, light weight, easy operation, etc., suitable for a variety of industrial fields, including chemical, building materials, power stations, glass and other industries of ventilation, environmental protection engineering.

This type of butterfly valve is usually controlled by a pneumatic actuator and can be quickly switched on and off to adapt to different process requirements. The body material of pneumatic butterfly valve is various, which can be carbon steel, manganese steel, stainless steel or heat-resistant steel to adapt to different media and temperature conditions.

Pneumatic dust butterfly valves are available in a wide range of sizes from 2 inches to 100 inches (DN50 to DN2500), with pressure classes of 10LB (PN1 to PN2.5) and operating temperatures from -20°C to +425°C. Its leakage rate is divided into two types: the ordinary type is less than or equal to 2%, and the low leakage type is less than or equal to 1%.

In the design and manufacture, the pneumatic butterfly valve follows a series of national standards, such as GB/T12238-1989, JB/T8692-1998, etc., to ensure the quality and performance of the product. In addition, the sealing performance of the pneumatic butterfly valve is good, which can be applied to the truncation and control of powder or granular materials, and is widely used in powder and granular material processing plants, especially when it is necessary to truncate gravity conveying or pneumatic conveying dry materials.

Pneumatic butterfly valve design features include:

Half shell made of high pressure aluminum alloy die casting
Turntables can be cast iron, engineering plastic or stainless steel
Seals for standard or food grade applications
Simple structure and easy maintenance
Lightweight and easy to operate
In addition, the pneumatic butterfly valve also has the following advantages:

High wear resistance
Easy to install
Short maintenance time
Low operation and maintenance costs
The working principle of the pneumatic butterfly valve is that by rotating the actuator, the butterfly plate rotates 90 degrees in the pipeline, so as to realize the opening or closing control of the medium flow. The butterfly valve plate is always located in the flowing medium, so regardless of the valve position, there will be a pressure drop in the flow.

When selecting a pneumatic dust butterfly valve, it is necessary to consider its applicable media, temperature, pressure and other parameters to ensure that the valve can work normally under specific process conditions.
