What does the price of electric wafer butterfly valve mean? When the excitation frequency is lower than the natural frequency of the mass (equipment) butterfly valve system, the electric butterfly valve does not play the role of vibration isolation; When the excitation frequency is close to the natural frequency, the vibration will be amplified; Only when the excitation frequency is greater than the square root of the natural frequency, can the electric butterfly valve have the effect of vibration reduction
Generally, the excitation frequency is required to be 2~3 times greater than the natural frequency to obtain good vibration isolation effect
