The HBS-C, SIB-C, HBS-D, and SIB-D ball valves are designed with a housing and 2 screwed-in connection pieces. The stem is blow-out proof and externally mounted up to DN 25. Thanks to the socket/spigot connection variant, quick installation into corresponding high-pressure piping systems is possible. With the optional safety locking handle (Type SIB), in addition to the single-sided detent in the closed position, a double-sided fixation of the positions can also be achieved. Also available with lockability.
