All you need to know about butterfly valve

1. All you need to know about butterfly valve A butterfly valve is a quarter-turn rotational motion valve, which is used for isolating or regulating flow. The butterfly valves can be automatic or operated by handles and are popular due to lower costs, lightweight, low maintenance qualities, and availability in required sizes from small to very large. According to the customer’s specifications, the butterfly valve manufacturers can provide the specific valve. Types of butterfly valves On the basis of body type, and disc alignment, the butterfly valve comes in diverse designs and sizes. Some of them are given below: On the basis of body type Wafer type- These valves are relatively cheaper and lighter than other types of butterfly valves. They contain two or more centering holes to help in easy installation. Wafers can’t be used as pipe ends or as end-of-line services. Lug type- Lug valves have threaded bolt holes around the entire area to connect with pipe flanges. They can be used as a pipe end or as end- of-line services. Flanged type- In this type of valve, the body has flanged on both sides that match with pipe flange dimension. Flanged types of valves are available in very large sizes. On the basis of disc alignment Zero offset- These valves have concentric design. The disc and stem are centered in the body of valve. Double offset- These valves are designed with double offsets of the stem. Double offset valves are considered as high-performance butterfly valves.

2. Triple offset- These valves are designed with three offsets. They provide tighter sealing than the other two types. Application of butterfly valves •Butterfly valves are often the best choice for household application such as domestic water supply system, irrigation & gardening system, aquarium piping, drainage system, as it regulates the water flow very efficiently. It prevents any fluid from passing through the pipe by using a circular disc to close off the section of piping. •Butterfly valves are commonly used in oil or gas refineries. Refineries plant uses high performance and fire-safe valves to regulate upstream, downstream, or midstream flow. Pipelines of pressurized air or other gases can be protected using a butterfly valve. •These valves are also found its application in the food processing sector. A highly certified food grade valve is used in breweries and other food processing industries to regulate fluid flow. Butterfly valves are ideal for systems with space restrictions.
