The central component is a circular disc, often called the "butterfly," which is mounted on a rotating stem (valve shaft) inside the pipe.

The valve's open position corresponds to the disc being parallel to the flow, while the closed position corresponds to it being perpendicular.

When selecting a butterfly valve, factors such as fluid type, pressure, temperature, and application environment need to be considered. We recommend consulting a professional for the best advice.

Butterfly valves require regular inspection and cleaning to ensure proper operation. Maintenance frequency should be increased, especially in corrosive or high-temperature environments. Using high-quality materials can reduce maintenance frequency and lower costs.
