Introducing the state-of-the-art AOC-6843 series, a remarkable development in cage guide control valves designed for large Cv values and exceptional dynamic stability, perfectly engineered for an array of heavy-duty applications. Distinguished by its pressure balanced type trim, this series is the ideal choice for managing high-pressure drops. Elevate your operational efficiency with the AOC-6843L//D/E series, which offers advanced solutions to meet low noise and anti-cavitation demands. This is achieved by incorporating sophisticated multi-hole type cages, replacing the standard ones found in traditional AOC-6843 series valves, while ensuring that all other components remain interchangeable with the original series. For unparalleled performance in the most challenging fluid conditions, consider the superior SNT LIMIPHON control type, designed to handle the toughest scenarios.
