The ARI-PRESO is a self-actuated surplus / pressure-sustaining valve that opens to discharge fluid whenever upstream pressure exceeds the set point — protecting the upstream side rather than the downstream. Used in pump bypass, accumulator stations and process pressure relief duty. 1.0619+N Cast Steel body, PN40 DN50.
