Pneumatic conveying is powered by compressed air , conveying powdery materials from one end to the other end in a closed container. Pneumatic conveying is widely used in fly ash and furnace slag in coal power plant.
The ceramic lined knife gate valve is suitable for the medium with high hardness or soft particle,such as dry ash ,ash water and so on .The working pressure class is class 150 ,air source pressure is from 0.6Mpa to 0.8Mpa.
Reasonable valve structure design is very important in pneumatic conveying system . The valve is full port design with out any block ,with anti-abrasive and nice sealing performance. It operated with less starting torque and avoid any ash blocking and scaling .Pneumatic ceramic lined knife gate valves widely work as shut off valve above the ash tank and vertical pipe line . As engineering ceramic is applied ,so it has longer life time than metal seated knife gate valve .
