The AOC-6843 series represents the forefront of our innovative cage guide control valves, known for their impressive large Cv value and exceptional dynamic stability. These valves are expertly crafted to handle a wide range of demanding heavy-duty services with ease. Key to their superior performance is the pressure balanced type trim, specifically engineered for managing high pressure drops. In the specialized AOC-6843L//D/E series, we've introduced advanced control valves that address challenging low noise and anti-cavitation requirements. This is achieved by integrating multi-hole type cages, a significant advancement over the standard cages used in the main AOC-6843 series cage guided control valves. The ingenious design ensures all components, excluding the multi-hole cage, are fully interchangeable with the AOC-6843 series parts, enhancing versatility and convenience. For extreme fluid conditions that surpass the capabilities of this series, we recommend the SNT LIMIPHON control type, designed for optimal performance in the most severe environments.
