SNC Valve

The SNC valves, patented by Dott.Ing.Mario Cozzani s.r.l., are characterized by a special spring shape, that along the entire length is able to assure no contact between all the coils. This original feature combined with the use of thermoplastic washers and caps, preventing the wear between the spring and its housing, ensures the highest reliability of the springing system.

Thanks to their feature, the SNC valves are particularly suited to work at high and variable speed, also in oil free applications. The optimised springing system of the SNC type is applicable to a wide range of Cozzani valves, such as DEA, PDLT, CPT, and others, achieving a considerable increase of the valve lifetime.
