Introducing the AOC-6843 series, the pinnacle of cage guide control valves, designed to deliver unparalleled performance with its impressive large Cv value and dynamic stability. Ideally crafted for the most demanding heavy-duty services, this series stands out with its pressure-balanced type trim, expertly designed to handle high-pressure drops with ease. The AOC-6843L//D/E series redefines control valves by incorporating advanced multi-hole type cages, meeting the critical demands of low noise operations and anti-cavitation requirements. These innovative cages replace the standard cages in the AOC-6843 series, ensuring enhanced performance while maintaining full interchangeability with the other parts of the series. When confronted with extremely severe fluid conditions beyond the scope of this series, we recommend the specialized SNT LIMIPHON control type for optimal performance.
