Features of air butterfly valve electric butterfly valve:
The air butterfly valve can isolate high-frequency vibration and has good sound insulation effect. The air butterfly valve is composed of air and has small internal friction, and will not affect the ability to isolate high-frequency vibration due to the inherent vibration of the butterfly valve itself. In addition, the air butterfly valve has no metal to metal contact, so it can sound insulation and sound proof effect is also very good.
The damping effect of air can be used to add an orifice between the air butterfly valve and the additional air chamber. When the load on the spring vibrates, the air flows through the orifice and has energy loss, thus playing the role of vibration attenuation.
