Ball Valve, Butterfly Valve, Solenoid Valve Selection Difference

When selecting a valve for a specific application, it is important to consider the requirements of the working conditions. Firstly, the pipeline flow must be taken into account. Solenoid valves are suitable for smaller calibers, typically less than 50, and are ideal for high-frequency operations and clean media. On the other hand, ball valves and butterfly valves are better suited for larger calibers. Ball valves have the advantage of being two-way, while solenoid valves are one-way. Ball valves can handle medium requirements that include sewage and small debris.

Butterfly valves, as their name suggests, have a butterfly-like shape. They are lighter and smaller compared to ball valves, making them more cost-effective for installation. However, their lifespan is not as long as that of ball valves. Butterfly valves are mostly unidirectional, although there are some bidirectional options available on the market. The cost of installation and control of ball valves differs from that of butterfly valves, as does the frequency of their use. Ball valves have a longer service life compared to butterfly valves, with industrial-grade designs lasting over 80,000 cycles.

In recent years, there have been advancements in butterfly valve technology, such as the development of high-performance butterfly valves. These valves can withstand up to 1 million cycles, whereas other types of butterfly valves typically have a service life of 2-30,000 cycles. However, ball valves still outperform butterfly valves in terms of longevity.
