Introducing the cutting-edge AOC-6843 series, a marvel in cage guide control valves engineered for exceptional performance, even under demanding conditions. Infused with a large Cv value, this series thrives on delivering dynamic stability, perfectly suited for an array of heavy-duty applications. Meticulously crafted with a pressure-balanced trim, it capably manages high-pressure drops with ease. Elevating the AOC-6843 series to new heights, the AOC-6843L//D/E variants incorporate innovative multi-hole type cages. These unique features achieve remarkable control valves that excel in minimizing noise and combating cavitation, surpassing standard cage designs. Remarkably, all components, save for the custom multi-hole cage, interchange seamlessly with standard AOC-6843 parts. For those extreme fluid situations beyond this series' capability, SNT's LIMIPHON control type remains the ideal solution.
