The butterfly valve has simple structure, small volume, light weight and few components. It can be made up of several key components. It is very convenient to open the butterfly valve. It only needs to select the switch to 90 degrees. The butterfly valve has a very good control of the fluid. It can increase or decrease the flow rate at any time. The valve has a certain resistance when transporting any fluid. The resistance of butterfly valve mainly comes from itself, such as the thickness of butterfly valve body. If you want to reduce the resistance to fluid, you only need to reduce its thickness.
Elastic seals have temperature limitations.
Butterfly valves have a wide range of applications. If they are used to control flow, different types and sizes of valves need to be selected, because butterfly valves are more suitable for larger caliber valves when they are designed. Butterfly valves are not only widely used in petroleum, gas, chemical industry, water treatment and other general industries, but also used in the cooling water system of thermal power plants.
