Why is a butterfly valve preferred in high-pressure applications?

In high-pressure applications, the preference for a butterfly valve is often attributed to its lightweight design and space efficiency. Butterfly valves use a disc that rotates on a shaft to control flow, which allows them to be constructed with less material than many other types of valves. This lightweight characteristic not only makes installation and maintenance easier but also reduces the overall load on the piping structure.

Additionally, the compact design of butterfly valves means they fit into tight spaces and can be used in applications where there are constraints on size and weight. This aspect can be crucial in high-pressure systems where maintaining structural integrity and minimizing weight are significant considerations.

While complete shutoff, the ability to handle temperature fluctuations, and sealing capabilities are all important features of valves in high-pressure applications, the standout advantages of a butterfly valve are its low weight and compact design, making it a preferred choice in many scenarios.
