Safety valves made of gunmetal,
angle-type with threaded or clamp connections

The technical features of the valve series 642 and 645 form the basis of the extended product range in which connection flexibility and corrosion resistance are paramount. The two-piece construction of the valve housing allows many different connection types to be used on the valve inlet. The inlet nozzles and the inner parts coming into contact with the media are made from highly corrosion-resistant stainless steel, which enables the valves to be used in an even wider range of applications.
