Ceramic star valve is the main equipment for dust removal equipment and other equipment feeding, suitable for powdered and granular materials. It is widely used in environmental protection, metallurgy, chemical industry, grain, food and other industrial sectors. It has a compact structure, beautiful appearance, and convenient use.
Its characteristics are smooth operation and low noise. Due to the distance between the bearings and the gearbox from the housing, there is a significant improvement in high temperature and lubrication.
