The AOC-6843 series represents the pinnacle of innovation in cage guide control valves, boasting a substantial Cv value and unparalleled dynamic stability. This state-of-the-art series is adeptly designed for an extensive range of heavy-duty applications. Its standout feature is the pressure-balanced trim, engineered specifically for high-pressure drops. Meanwhile, the AOC-6843L//D/E series elevates performance by offering control valves that meet stringent low-noise and anti-cavitation standards. This achievement is made possible by integrating multi-hole type cages, a sophisticated upgrade from standard cages, into the AOC-6843 series. The beauty of this design lies in its interchangeability; all components, aside from the multi-hole cage, are seamlessly interchangeable with the AOC-6843 series. For extreme fluid conditions beyond this series' scope, we recommend opting for the SNT LIMIPHON control type to ensure exceptional performance.
