Where is the butterfly valve used

Posted by Bundor valve
Butterfly valve is one of the most commonly used valves in the pipeline system, its application is very wide, not only can be used to cut off the flow medium in the pipeline, but also can be used to do flow regulation.When the fluid in the pipeline passes through the butterfly valve, the pressure loss is about 3 times that of the gate valve.So the choice of butterfly valve to consider two factors, one is the pressure loss of the pipeline system, the second is when the butterfly valve is closed, butterfly plate under the pressure of the pipeline medium and resilient seat material can bear how much temperature.

Butterfly valve structure length is short, the overall height is also small, short operating torque, can be fast opening and closing, can be a good fluid control, butterfly valve structure principle makes it most suitable for the production of large diameter valves.When butterfly valves are required for flow control, the correct size and type of butterfly valve should be selected for effective operation.

Where is the butterfly valve used

1. It is required to throttle, adjust and control the pipeline, and the valve structure is required to have short length and fast opening and closing speed.Butterfly valves are recommended.

2. Butterfly valve can be used in pipelines requiring double-position adjustment and shrinkage, which require low noise, cavitation and a small amount of leakage into the atmosphere and corrosive circulation media.

3. Under special working conditions with strict requirements on sealing, low temperature containing impurities and easy to cause wear, butterfly valve is recommended to be used, and three-eccentric or double-eccentric butterfly valve with metal sealing shall be used.

4. In petroleum, petrochemical, chemical industry, metallurgy, electric power and other fields, recommend the use of metal hard seal triple eccentric butterfly valve, in many cases, can replace the use of gate valve, globe valve.

5. The middle line butterfly valve is suitable for the working environment with strict requirements on sealing performance and zero leakage. The middle line butterfly valve is most suitable for the pipeline of fresh water, sewage, seawater, brine, steam, natural gas, oil and various acid and alkali media at the operating temperature of -10-150℃.

6. Double eccentric butterfly valve is very suitable for use in urban heating, gas supply, water supply and gas pipelines, as a device to stop or regulate flow.

7. Eccentric soft seal butterfly valve is widely used in metallurgical, light industry, electric power and petrochemical systems of gas pipelines and waterways.It is used as two-way opening and closing and adjustment of ventilation and dust removal pipelines.
