Introducing the AOC-6843 series, our groundbreaking addition to the realm of cage guide control valves. Engineered with precision, this latest series boasts an exceptional large Cv value combined with dynamic stability, making it the perfect choice for a myriad of heavy-duty applications. Distinguished by its pressure-balanced type trim, the AOC-6843 series excels in handling high-pressure drops with ease. To address specific low noise and anti-cavitation demands, the AOC-6843L//D/E variants elevate performance by employing innovative multi-hole type cages, a remarkable enhancement over the standard cage designs. Importantly, all other components remain fully interchangeable with those of the standard AOC-6843 series, ensuring seamless integration and maintenance flexibility. For extreme fluid conditions that surpass this series' capabilities, we recommend the SNT LIMIPHON control type as an optimal choice.
