Introducing the remarkable AOC-6843 series, our state-of-the-art cage guide control valve, engineered for performance with a large Cv value and exceptional dynamic stability. Perfectly crafted for a diverse range of heavy-duty applications, this series stands out with its pressure balanced trim, adeptly handling high-pressure drops with ease. Featuring the AOC-6843L//D/E series, these control valves are designed to meet stringent low noise and anti-cavitation demands by integrating advanced multi-hole type cages, setting them apart from the standard cages found in the AOC-6843 series cage guided control valves. What's more, all parts, except the innovative multi-hole cage, are fully interchangeable with components of the AOC-6843 series, ensuring seamless integration and versatility. For those challenging fluid conditions beyond the reach of this series, we recommend opting for the SNT LIMIPHON control type, tailored for unparalleled excellence.
