About products
Introducing the AOC-6843 series, our most advanced cage guide control valves boasting a large Cv value and exceptional dynamic stability. Engineered for a multitude of heavy-duty applications, this series is defined by its pressure-balanced type trim, adeptly handling high-pressure drops. The standout AOC-6843L//D/E sub-series elevates performance by integrating multi-hole type cages, which fulfill stringent low noise and anti-cavitation criteria, supplanting the standard cages found in the AOC-6843 series. Notably, all components, aside from the multi-hole cage, are seamlessly interchangeable with the standard series parts, ensuring compatibility and ease of maintenance. For fluid conditions beyond the capabilities of this exceptional series, we recommend the SNT LIMIPHON control type to expertly meet your needs.
