وصف
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 1.4581 Stainless Steel model is rated to PN40 DN80 and is suitable for steam, compressed air, industrial gases and clean water service.
