The CSA Mod. Ventolo—with body in ductile cast iron, and internals and float in stainless steel—automatically releases air pockets accumulated on critical points of the pressurized pipeline, like high points and changes in slope. These releases avoid unwanted head loss and reduction in flow through the system.
Thanks to the lever mechanism, the float force is multiplied so to reach low sealing pressure values. The valve will guarantee a high accuracy, also in case of low flow rate conditions, drastically reducing the maintenance operations.
