Introduction: This article mainly introduces the main drawbacks of electric gate valves, and hopes the relevant readers will gain something!
1. The shape design has a high dimension and a long time of starting and closing. When opening, the valve plate needs to be lifted to the upper part of the valve chamber. When the valve plate is closed, the valve plate needs to be completely dropped into the valve seat. Therefore, the valve plate has a large opening and closing stroke and takes a long time.
2. Since the two sealing surfaces of the valve plate and the valve seat of the electric gate valve have friction during the opening and closing process, the sealing surface is easily scratched, which affects the sealing performance and service life, and is not easy to maintain.
