DS (3 / 6 / 9) 43h flange triple eccentric hard seal butterfly valve

Product Overview

explain

Triple eccentric hard seal butterfly valve is a new type of butterfly valve designed by our company for high temperature, high pressure and obvious erosion pipelines with advanced triple eccentric structure.

purpose

The three eccentric hard seal butterfly valve is mainly used in the pipelines of petroleum, chemical industry, metallurgy, water heating, water and electricity with obvious high temperature, high pressure and erosion phenomena as a component for on-off and flow control of the pipeline system.

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.
