Butterfly valves have a simple structure, small size, light weight, and relatively few components. Only a few key parts can form a butterfly valve, which is very convenient to open. Simply select the switch to 90 degrees. Butterfly valves have excellent control over fluids, and can increase or decrease flow at any time.
Valves have a certain resistance when transporting any fluid, and the resistance of butterfly valves mainly comes from themselves, such as the thickness of the butterfly valve body. If you want to reduce the resistance to fluids, you only need to reduce its thickness.
Elastic seals have the drawback of being limited by temperature.
The application range of Worm Gear Operated U Flange Lined Butterfly Valve is also relatively wide. If it is used to control flow, different types and valve body sizes need to be selected because butterfly valves are designed to be suitable for valves with larger diameters. The valve is widely used not only in general industries such as petroleum, gas, chemical, and water treatment, but also in cooling water systems for thermal power plants.
