Metal butterfly valve

Metal butterfly valves have been developed as the new standard for double eccentric high-performance butterfly valves. These valves are used in high pressure and severe conditions. This product is the result of an integrated approach that gives the valve the highest level of efficiency, with many innovations that complement each other. Particular emphasis was placed on design flexibility to meet customer requirements. The technical and economic advantage of time-honored technology has led to increased service life, increased productivity and safety.
