Introducing the AOC-6843 series, our latest innovation in cage guide control valves, designed to deliver outstanding performance with an impressively large Cv value and remarkable dynamic stability. Ideal for a wide range of heavy-duty applications, this series is engineered with a pressure balanced type trim, expertly crafted to handle high-pressure drops. The AOC-6843L//D/E series elevates control valve solutions by integrating multi-hole type cages to meet stringent low noise and anti-cavitation standards, surpassing the capabilities of standard cages found in the original AOC-6843 series. Remarkably, all components, aside from the multi-hole cage, are fully interchangeable with parts from the AOC-6843 series, ensuring seamless integration and versatility. For even more demanding fluid conditions, we recommend the superior SNT LIMIPHON control type to meet your specific requirements.
