Introducing the AOC-6843 series, our state-of-the-art cage guide control valve with an impressive large Cv value and exceptional dynamic stability. Designed for a multitude of heavy-duty applications, this series showcases a unique pressure-balanced trim that delivers optimal performance even under high-pressure drops. The AOC-6843L//D/E variants are engineered to address specific low noise and anti-cavitation needs, featuring advanced multi-hole type cages in place of the standard ones found in the AOC-6843 lineup. Remarkably, all components except the multi-hole cage are fully compatible with the standard AOC-6843 series parts, ensuring seamless integration. For the most challenging fluid scenarios beyond the capabilities of this series, explore our SNT LIMIPHON control type for unmatched precision and reliability.
