Introducing the remarkable AOC-6843 series, our latest innovation in cage guide control valves designed for large Cv value and exceptional dynamic stability. Perfectly tailored for a wide array of heavy-duty services, this series stands out with its pressure balanced type trim ideal for managing high pressure drops with ease. Experience unparalleled performance with the AOC-6843L//D/E series, offering advanced control valves that fulfill stringent low noise and anti-cavitation standards. This is achieved through the innovative use of multi-hole type cages, replacing the standard cages found in the AOC-6843 series cage guided control valves. We ensure compatibility and ease of maintenance, as all parts except the multi-hole cage are entirely interchangeable with those of the AOC-6843 series. For the most extreme fluid conditions that extend beyond the capabilities of this series, we recommend opting for the SNT LIMIPHON control type, specifically engineered for such demanding applications.
