Welflex butterfly valves triple eccentric HP
Triple eccentric butterfly valves have an additional eccentricity compared to double eccentric butterfly valves. In addition to the fact that the blade is displaced axially with respect to the shaft and the shaft itself is displaced with respect to the center (the first two eccentricities), a third eccentricity is applied by adjusting the seating surface.
The result is lower friction during valve closure, which provides a better seal and less wear in the long run.

Application
Because triple eccentric butterfly valves have a better seal and less long-term wear, these valves are widely used in steam applications and other demanding conditions where long-term performance without maintenance is required. However, there is debate about the applicability of these valves in contaminated mediums. Our specialists are happy to provide tailored advice.
