Advantages of Wafer butterfly Valve
Compact structure, space saving
The wafer design makes the valve small and light, especially suitable for pipeline systems with limited space.
Easy installation
The wafer butterfly valve is clamped between the pipe flanges by bolts, without additional flanges, and is easy to install and disassemble.
Low cost
Simple structure, low material consumption, low manufacturing cost, and reduced installation and maintenance costs.
Flexible operation
The butterfly plate can be quickly opened and closed by rotating 90 degrees, which is simple to operate and suitable for occasions that require frequent switching.
Small flow resistance and good flow control
When fully open, the butterfly plate has little obstruction to the flow of the medium, low pressure loss, and is suitable for large flow applications.
Good sealing performance
Soft seals or metal seals are used, with excellent sealing performance, which can meet the needs of different media and working conditions.
Easy maintenance
Simple structure, few parts, easy maintenance and replacement of seals, and long service life.
Wide range of application
It can be used for water, air, gas, oil and corrosive media, and is widely used in water treatment, chemical industry, HVAC, food and other industries.
A variety of material options
The valve body, butterfly plate and sealing materials can be selected according to the characteristics of the medium to meet the needs of different working conditions.
Wafer butterfly valve is an ideal choice in pipeline system due to its compact design, low cost, easy operation and wide applicability.
