The air butterfly valve is a kind of non-metallic butterfly valve that adds pressure air into a flexible closed container, and uses the water temperature recovery when the air is compressed to provide elasticity, so as to achieve vibration isolation and buffering. The electric butterfly valve of the air butterfly valve has variable stiffness characteristics, easy to obtain low natural frequency (2.6-5.3Hz), high damping ratio (0.06-0.08), and the valve efficiency can reach more than 95%
HSD low-frequency air butterfly valve The electric butterfly valve adopts a support design inside, which improves the use stability
