This Prevost flanged ball valve body handles 6 inch aluminum air pipe, the largest size in the PPS1 range, and is normally used to isolate a main header rather than a branch. A quarter-turn of the handle gives a full-bore, low-restriction path when open and a positive seal when closed.
It bolts into the flanged connections of the Prevost aluminum air piping system and sits among the wider range of shut-off valves we stock.
