About products
Introducing the AOC-6843 series, our state-of-the-art cage guide control valve renowned for its exceptional large Cv value and unparalleled dynamic stability. Engineered to withstand a diverse range of heavy-duty applications, this series boasts a pressure balanced type trim that deftly handles high pressure drops. The AOC-6843L//D/E series elevates control performance by integrating advanced multi-hole type cages, designed to fulfill low noise and anti-cavitation demands, as an alternative to standard cages in the AOC-6843 series. An impressive feature is the interchangeability of all components, with the multi-hole cage being the sole exception, linking seamlessly with the AOC-6843 series parts. For extraordinarily severe fluid conditions beyond this series' capabilities, we recommend selecting the SNT LIMIPHON control type for optimal results.
