Description
Prevost PPS1 RSI AL Aluminum-Body Shutoff Valves

Frequently Asked Questions
Does a matching inch size guarantee compatibility?
No. Pipe sockets, CC interfaces, flange connections, NPT threads, BSPP threads and mounting threads serve different purposes. Use the exact model specifications.
