About products
Introducing the AOC-6843 series - our state-of-the-art, cage guide control valve, boasting an impressive large Cv value and dynamic stability. Perfectly engineered for a wide array of heavy-duty services, this series stands out with its pressure balanced trim tailored for high-pressure drops. The AOC-6843L//D/E series elevates control valves to new heights, offering solutions that satisfy low noise and anti-cavitation needs. This is achieved by integrating innovative multi-hole type cages, which replace the conventional cages found in our AOC-6843 series. Remarkably, all components, except for the multi-hole cage, can be seamlessly interchanged with parts from the AOC-6843 series. For those extreme fluid conditions beyond the reach of this series, we recommend selecting the SNT LIMIPHON control type for unparalleled performance.
