The AOC-6843 series stands as a pinnacle of engineering excellence, embodying our latest advancements in cage guide control valve technology designed for impressive Cv values and dynamic stability. Perfectly suited for a wide array of heavy-duty applications, this innovative series showcases a pressure-balanced type trim that is adept at managing high pressure drops. Elevating performance further, the AOC-6843L//D/E series integrates cutting-edge multi-hole type cages, effectively meeting stringent low noise and anti-cavitation standards, setting it apart from standard cage configurations. Notably, all components, except the multi-hole cage, are seamlessly interchangeable with those in the AOC-6843 series. For the most challenging fluid conditions beyond the scope of this series, we recommend opting for the SNT LIMIPHON control type, to ensure optimal performance and reliability.
