Triple eccentric butterfly valves

The triple-eccentric high-performance valves are designed for easy maintenance and maximum operational reliability. The swivel shaft limiter and the visual position indicator on the shaft ensure that the damper remains in the correct position even during servicing and that incorrect positions are avoided. In addition, the robust shaft seal in accordance with the TA-Luft standard ensures long-lasting tightness and significantly reduces maintenance work. These sophisticated features not only make servicing easier, but also make a decisive contribution to the durability and reliability of the butterfly valve in demanding applications.

The lamella seat of our triple-eccentric high-performance butterfly valves ensures a leak-free seal in both pressure directions thanks to the stainless steel/graphite lamella seal and remains completely tight at temperatures from - 50 °C to + 400 °C. Thanks to the eccentric design and the fixed offset angle to the sealing surface, the butterfly valve operates friction-free and without a clamping effect. The seat ring is integrated into the body, which prevents one-sided wear and enables a flexible, self-centring seal. This achieves maximum tightness in accordance with DIN EN 12266 part 1, leakage rate A, with minimum switching torque.
