Features

Friction-free seal: Thanks to the triple-eccentric design, the triple-eccentric butterfly valve has almost no friction when opening and closing. This not only extends the life of the sealing surface, but also improves the sealing performance of the valve and avoids common seal failure problems.

High temperature and high pressure resistance: The sealing material of hard-sealed butterfly valves is usually metal or carbide, which allows it to withstand extreme high temperature and high pressure environments. In contrast, soft-sealed butterfly valves may fail due to aging or deformation of the sealing material at high temperatures, while hard-sealed butterfly valves can continue to work stably under harsh conditions.

Strong corrosion resistance: Since the sealing material of the triple eccentric butterfly valve can be corrosion-resistant metal or alloy, it is suitable for handling corrosive media, such as acids, alkalis and other chemical substances. Compared with soft-sealing butterfly valves, it is more durable in corrosive media.

Long service life: The triple eccentric butterfly valve will not fail due to wear when sealing, so it can still maintain a long service life even under frequent opening and closing operations. This is especially important for systems requiring high frequency operation.

High sealing reliability: The triple eccentric design allows the sealing surfaces of the butterfly plate to automatically come together when closing, achieving a self-locking function and ensuring no leakage of media. This design greatly improves the sealing reliability of the valve and is especially suitable for working conditions requiring zero leakage.
