explain:

Welded butterfly valve is a new type of three eccentric hard seal butterfly valve that our company has accumulated many years of experience in butterfly valve production and has been improved and optimized countless times.

purpose:

Because of its unique valve body structure and simple and effective connection mode, welded butterfly valves are widely used in harsh working conditions such as chemical industry, metallurgy, power plant and water heating as important equipment for on-off and flow regulation.

Product features:

The valve body and valve seat of the three eccentric hard seal butterfly valve are of a connected structure. There is a certain eccentric distance between the center of the valve stem, the center of the sealing surface and the center of the valve body. There is an offset angle between the sealing surface and the center line of the valve body, so that there is no friction between the butterfly plate and the valve body when the valve is opened and closed, thereby extending the service life of the valve.
