Construction Features
The Air operated ball valve series are designed for
controllingthe powders containing dusts or solid bodies, especially
for thosefields or systems as coal-powder injection in
high-furnace, airflowlines, lance lines, etc.
1.Wear-auto-compensation equipment is applied with the valveseat to
effectively ensure the sealing performance of the valve.
2.The seal ring made from exotic materials features such spe-c
ialties as high-temperature resistance,abrasion-resistance,
longservice-life, etc.
3.The valve bears those characteristics like compact
structure,flexible on-off, and convenient method for installation
and mainte-nance.
