The AOC-6843 series represents the pinnacle of our innovation in cage-guided control valves, boasting an impressive large Cv value and dynamic stability, making it an ideal choice for a range of demanding heavy-duty applications. This series is ingeniously designed with a pressure-balanced trim, enabling it to handle high-pressure drops with ease. Additionally, the AOC-6843L//D/E series is engineered to meet stringent low noise and anti-cavitation requirements by utilizing advanced multi-hole type cages. These cages replace the standard ones in the traditional AOC-6843 series, offering a superior solution for noise reduction and cavitation prevention. Notably, all components, aside from the multi-hole cage, are perfectly interchangeable with those of the AOC-6843 series, ensuring seamless integration. For extreme fluid conditions beyond this series' capabilities, we recommend opting for the SNT LIMIPHON control type, designed for exceptional performance.
