Introducing the AOC-6843 series, a groundbreaking innovation in our lineup of cage guide control valves. Engineered with a substantial Cv value, this series excels in dynamic stability and is perfectly crafted for a diverse range of heavy-duty applications. The defining feature of this series is its pressure-balanced type trim, designed to adeptly manage high-pressure drops with ease. Elevating the standard, the AOC-6843L//D/E series revolutionizes control valves by integrating multi-hole type cages, catering to low noise and anti-cavitation needs, unlike the conventional cages found in the AOC-6843 series. Furthermore, all components excluding the multi-hole cage are designed for seamless interchangeability with AOC-6843 series parts. For exceptionally challenging fluid conditions beyond this series, we recommend selecting the SNT LIMIPHON control type, ensuring comprehensive coverage.
