The AOC-6843 series represents the pinnacle of our cage guide control valve technology. Engineered with a robust large Cv value, it guarantees outstanding dynamic stability, making it ideal for heavy-duty applications. This remarkable series features a pressure-balanced trim, expertly crafted to handle high pressure drops with ease. Within this innovative range, the AOC-6843L//D/E series stands out by offering advanced control valves equipped with multi-hole type cages. These cutting-edge valves are designed to meet stringent low noise and anti-cavitation standards, outshining their standard cage counterparts. What's more, all components, except the multi-hole cage, are seamlessly interchangeable with those of the standard AOC-6843 series. For the most challenging fluid conditions that exceed this series' capabilities, we recommend the SNT LIMIPHON control type for superior performance and reliability.
