What does the specification and model of electric butterfly valve DN400 mean? Electric butterfly valve can isolate high-frequency vibration and sound insulation effect is good
The electric butterfly valve is composed of air and has small internal friction, which will not affect the ability to isolate high-frequency vibration due to the inherent vibration of the butterfly valve itself. In addition, the electric butterfly valve has no metal to metal contact, so it can sound insulation and sound proof effect is also very good.
