Eccentric butterfly valve

Eccentric butterfly valve

Eccentric butterfly valve is different from the concentric butterfly valve from the perspective of the specified structure. Actually, the specified structure has contributed a lot to the practical functions. And there is a variety of the types related to the eccentric butterfly valve. They are mainly the single eccentric butterfly valve, double eccentric butterfly valve and triple eccentric butterfly valve. These three types are doing great favors on the industrial development.

The single eccentric butterfly valve came into being to solve the unpleasant compression caused by the valve clack and the valve seat. It is particular because the axis of the valve stem is deviated from the center of the valve clack. As a result, it has effectively reduced the pressure on the valve seat, leading a longer life and better performance of the equipment.

And the double eccentric butterfly valve is the most popular type among the three major types. It has made a lot of improvements on the single eccentric butterfly valve. The axis of the valve stem is deviated from the center of the equipment. Therefore, the wear can also be greatly reduced in order to reach a good performance.

And for the triple eccentric butterfly valve, it has done a great job. At this time, this kind of eccentric butterfly is expected to solve the contradiction between the seal and the working condition. The hard seal is able to withstand high temperature but with a large leakage. And the soft seal is able to ensure no leakage but with the disability to withstand the high temperature. Therefore, the triple eccentric butterfly has successfully solved the unpleasant situation well through its specified structure.
