Advantages and disadvantages of butterfly valves

Advantages of butterfly valve:

1. Simple structure, small size, and light weight.

2. Under low pressure, good sealing can be achieved.

3. Easy and quick opening and closing, labor-saving, low fluid resistance, and can be operated frequently.

4. It can transport mud with minimal liquid accumulation at the pipeline outlet.

5. Good regulation performance.

The main Butterfly Valve product names of China Butterfly Valve Network include:Pneumatic Ventilation Butterfly Valve,Pneumatic High Vacuum Butterfly Valve,Pneumatic Desulfurization Wafer Butterfly Valve,Pneumatic Desulfurization Flange Butterfly Valve,Quick-installed Sanitary Butterfly Valve,Rectangle Louver Regulate Butterfly Valve,Rotundity Louver Electric Regulate Butterfly Valve,Spring(Emergency Off) Quick Off Butterfly Valve,Sanitary Butterfly Valve,Telescopic Butterfly Valve

Disadvantages of butterfly valves:

1. Poor sealing performance.

2. The pressure and working temperature range are small.

According to their structural form, butterfly valves can be divided into center sealed, single eccentric sealed, double eccentric sealed, and triple eccentric butterfly valves. The center sealed type belongs to an earlier form of butterfly valve; Compared with the center sealed butterfly valve, the single eccentric sealed butterfly valve has a more complex structure, slightly higher cost, better sealing performance, longer service life, and higher operating pressure; Compared with single eccentric butterfly valves, double eccentric and triple eccentric butterfly valves have more complex structures, higher manufacturing costs, better sealing performance, longer service life, and higher operating pressure.

The characteristics of industrial butterfly valves are high temperature resistance, high pressure range, large nominal diameter, carbon steel valve body, and metal ring instead of rubber ring for valve plate sealing. Large high-temperature butterfly valves are manufactured by welding steel plates and are mainly used for flue gas ducts and gas pipelines for high-temperature media.
