What is a Butterfly Valve and How Does it Work

butterfly valves are a family of quarter-turn rotational motion valves that are used in pipelines to shut-off flow. it is often said that butterfly valves can be used to regulate the flow. however, we do not recommend doing this, as it can damage the valve disk and have a negative effect on the sealing properties. they are used in a wide variety of process media and industries especially in water supply, collection, and distribution, as well as pumping stations, and have a broad range of use cases especially in flow isolation. a couple of their key advantages over other valve families are their simple construction and compactness, resulting in the end products being of lighter weights and lower cost and with smaller installation footprints and faster actuation speeds.

butterfly valves are used to prevent and isolate the flow of fluid in industrial sectors. they are easy to handle and very fast in stopping the flow. they are majorly preferred by the customers because of its low cost and light weight. there are different types of butterfly valves are available in the market for wide range of uses and pressures.

the leading manufacturers of awwa butterfly valve have to meet the standards and norms of awwa standard c504. every manufacturer assures that every design of valve is better than the previous one. awwa butterfly valve doesn't leak from anywhere and won't damage by corrosion.

how does butterfly valves work? 

a butterfly valve is designed to operate in the most adverse conditions and to perform well in high-stress situations. regardless of fluid direction, the edge of the discs will always be a little bit upstream, which is good in worst-case scenarios. these valves are very short and precise, which is why they are commonly used in industrial applications.

they are regarded as extremely dependable and effective, and they do not necessitate routine maintenance. they can be operated in all modes, including manually, automatically, and pneumatically. because automatic valves are long-lasting, they contribute to lower operational costs. a variety of materials are used in the construction of the awwa butterfly valve to ensure that it performs optimally. each material has its own set of advantages and disadvantages. carbon steel is preferred for the manufacture of the valve and seat because it provides customers with cost-effective solutions.

carbon steel only has a major disadvantage: it corrodes easily. however, this is easily remedied by painting its surface. these butterfly valves can also be made of stainless steel. there are numerous stainless steel versions available on the market, including austenitic, duplex, ferritic, and many others. these valves’ low maintenance and operational costs extend their life-cycle and save customers’ time, which is typically lost during maintenance.
