Butterfly valves are very precise, which makes them advantageous in industrial applications. They are quite reliable and require very little maintenance. Butterfly valves offer true isolation and control capabilities in a single product. Designed for accurate flow and pressure control, they are ideal in applications where positive isolation is required.
Butterfly valves are used where space is limited. Unlike gate valves, butterfly valves can be used for throttling or regulating flow as well as in the full open and fully closed position. The pressure loss through a butterfly valve is small in comparison with the gate valve.
