The Prevost PPS1 RSI AL is an aluminum-body shut-off valve for larger runs of PPS aluminum air pipe, offered in 2 inch, 2 1/2 inch and 3 inch with either a female NPT and clamp connection or clamp on both sides. The aluminum body keeps weight down on overhead headers compared with a cast iron or brass valve of the same bore.
It fits the Prevost aluminum air piping system and sits alongside the rest of our shut-off valves.
