Construction Features
The poweder-coal ejection ball series are designed for controling the powders containing dusts or solid bodies,especially for those fields or systems as coal-powder injection in high-furance,airflow lines,ect.
1.Wear-auto-compensation equipment is applied with the valve seat to effective ensure the sealing performance of the valve.
2.The seal ring made from exotic materials features such spe-cialties as high-temprature resistance,abrasion-resistance,long service-life,ect.
3.The valve bears the characteristics like compact structure,flexible on-off,and convenient method for installation and mainte-nance.
