Traditional valve, whether it is the butterfly valves, rotary valves, iris or other types of valves, there is great momentum powder flow when the brass ball valve is closed it is difficult to keep out of powder.
     Application of cone-shaped valve solved the problem of gravity. Powder flow of momentum from the closure of the power valve, but the old-fashioned conical valve will be in the external edge of the phenomenon of the small streams.
     New type of cone-shaped valve completely closed the brass angle valve before the edge from its reduced to just 15mm, the following powder residue after the complete closure of air-flow valves, so as to avoid the leakage phenomenon.
     Valves use a simple external sensor to change to bring a high degree of cone layer and with continuous adjustment of the function, can be done in accordance with the specific circumstances supporting the adjustment, such as the viscous material is not easy under the powder.
