The ARI-PREDU is a self-actuated pressure reducing valve that automatically maintains a stable downstream (reduced) pressure regardless of upstream variation or flow demand. No external power required — pilot operation uses the medium itself. This EN-JS1049 Nodular Iron model is rated to PN16 DN32 and is suitable for steam, compressed air, industrial gases and clean water service.
