Introducing the AOC-6843 series, the pinnacle of innovation in cage guide control valves with large Cv values, perfect for dynamic stability in varying heavy-duty applications. This series, masterfully engineered with pressure-balanced trim, excels in handling substantial pressure drops. Experience the AOC-6843L//D/E series, which elevates this excellence by offering low noise and anti-cavitation solutions, incorporating advanced multi-hole type cages instead of standard ones. Remarkably, all components, excluding the multi-hole cage, are designed to be interchangeable with parts from the AOC-6843 series. For extreme fluid conditions beyond the capabilities of this series, we recommend our SNT LIMIPHON control type for unparalleled performance.
