D (3 / 6 / 9) 43h American standard butterfly valve

Product Overview

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:

It adopts a three eccentric structure with reliable sealing performance, which ensures that the disc plate does not contact the sealing seat when it is opened, extends the service life, ensures reliable sealing performance, and has the advantages of high temperature resistance, wear resistance and corrosion resistance.
