About products
The AOC-6843 series introduces our state-of-the-art cage guide control valve with an impressive large Cv value, offering dynamic stability for a wide array of heavy-duty applications. This remarkable series features a pressure-balanced type trim, specifically engineered for managing high-pressure drops with ease. The AOC-6843L//D/E series elevates control valve performance by addressing low noise and anti-cavitation concerns through the integration of advanced multi-hole type cages, setting it apart from standard cage designs in the AOC-6843 series. Ingeniously designed, all components-aside from the multi-hole cage-are fully interchangeable with parts from the standard AOC-6843 series, ensuring consistent and flexible maintenance. For the most challenging fluid conditions beyond the scope of this series, we recommend selecting the superior SNT LIMIPHON control type to meet your precise demands.
