The SIBK-D ball valve is designed as a compact ball valve with a fixed plug socket integrated into the housing and a screwed-in connection piece. The stainless steel spindle is blow-out proof and externally mounted. The plug socket/plug nipple connection variant enables rapid installation in corresponding high pressure piping systems. The safety locking handle allows both one-sided locking in the closed position and two-sided fixation of positions. Also available with lockable feature.
