Dongfeng electric butterfly valve - butterfly valve damping electric butterfly valve - hanging electric butterfly valve manufacturer
The butterfly valve electric butterfly valve industry has existed for more than 100 years abroad, while the domestic electric butterfly valve industry is still in its infancy, lacking standards and specifications. After the market demand emerged in recent years, a large number of electric butterfly valve manufacturers have participated, with mixed production and quality, and many fake and inferior products filling the market. Customers who do not understand the electric butterfly valve are likely to be tempted to buy low-quality products at low prices. What are the characteristics of high-quality electric butterfly valves?
1、 The structural design is reasonable. At present, the mainstream electric butterfly valve products in the international market include: free butterfly valve electric butterfly valve, limit butterfly valve electric butterfly valve, and side limit butterfly valve. No matter what kind of structure, it is necessary to prevent rigid connection between structures to transmit vibration, and it is better to have a height adjustment design.
