Aeration butterfly valve is a control valve with simple structure ,it is also used to control switch for low pressure piping. It is widely used inChemical industry, building materials, power plant, glass and other industries
feature
Compact structure, light weight, easy installation, small flow resistance, big circulation, avoid high temperature expansion effect, convenient operation
There are no Connecting rodsand the bolts ,it is rliable operation, long service life,convinent Workstation installation.
It is widely used for Building materials, metallurgy, mining, power. The temperature of material should be less than ≤300℃, Nominal pressure should be 0.1Mpa.
