The butterfly valve shock absorber can effectively control the vibration and swing of various frequencies.
The butterfly valve damper industry has existed abroad for more than one hundred years, while the domestic damper industry is still in its infancy, lacking standards and specifications. After the market demand has emerged in recent years, a large number of electric butterfly valve manufacturers have participated, with mixed production and quality, many of them filling the market. Customers who do not understand the shock absorber are likely to be purchased with inferior products at low prices. The structural design is reasonable. At present, the mainstream butterfly valve shock absorber products in the international market are: free butterfly valve shock absorber, limit butterfly valve shock absorber, and side limit type. No matter what kind of structure, it is necessary to prevent rigid connection between structures to transmit vibration, and also have height adjustment design. Anti rust treatment shall be in place to ensure the service life of butterfly valve damper. At present, the surface treatment of mainstream electric butterfly valves includes hot-dip galvanizing, paint baking, painting, plastic spraying, etc. Zinc pad and baking varnish are preferred. Excellent performance. Many butterfly valve dampers have anti vibration elements.
