Our cutting-edge AOC-6843 series represents the pinnacle of innovation in cage guide control valves, offering superior performance with an impressive large Cv value and unrivaled dynamic stability. Designed for a spectrum of heavy-duty applications, this series excels with its pressure-balanced type trim to handle high pressure drops effortlessly. The AOC-6843L//D/E series elevates functionality by integrating advanced multi-hole type cages, specifically tailored for low noise and anti-cavitation needs, setting a new standard over conventional cages. Notably, every component, aside from the multi-hole cage, seamlessly interchanges with those in the AOC-6843 series, enhancing versatility and ease of maintenance. For those extreme fluid conditions beyond the scope of this series, trust in the SNT LIMIPHON control type to deliver superior results.
