About products
Introducing the AOC-6843 series, our latest innovation in cage guide control valves designed to deliver exceptional performance with large Cv values and remarkable dynamic stability. Tailored for a diverse array of heavy-duty services, this series stands out with its pressure-balanced trim, expertly engineered to handle high-pressure drops with ease. The AOC-6843L//D/E series elevates these control valves to new heights by incorporating advanced multi-hole type cages, catering to low noise and anti-cavitation needs, surpassing the capabilities of standard cages found in the AOC-6843 series. Ingeniously crafted for versatility, all components, except the multi-hole cage, are seamlessly interchangeable with those of the standard AOC-6843 series. For challenging fluid conditions that extend beyond this series' capabilities, we recommend opting for the SNT LIMIPHON control type, ensuring you have the precise solution for any demanding situation.
