The AOC-6843 series represents the pinnacle of our innovative cage guide control valves, boasting a large Cv value and remarkable dynamic stability. This series is expertly engineered for a multitude of heavy-duty applications, featuring pressure-balanced type trim designed to withstand high-pressure drops with ease. The AOC-6843L//D/E series elevates performance by integrating multi-hole type cages, which surpass the standard design, to meet stringent low noise and anti-cavitation demands. All components, excluding the multi-hole cage, are fully interchangeable with standard AOC-6843 series parts, ensuring seamless adaptability. For the most challenging fluid conditions not addressed by this series, we recommend selecting the SNT LIMIPHON control type for unparalleled performance.
