Introducing the AOC-6843 series, our state-of-the-art cage guide control valve, renowned for its impressive large Cv value and remarkable dynamic stability. Designed to withstand a broad spectrum of heavy-duty applications, this exceptional series boasts a pressure balanced type trim, perfect for managing high pressure drops. The AOC-6843L//D/E series elevates control performance by integrating multi-hole type cages, expertly crafted to meet stringent low noise and anti-cavitation standards. Unlike standard cages, these innovative components ensure optimal performance. Notably, all parts, except the multi-hole cage, are fully interchangeable with those in the AOC-6843 series, allowing for seamless integration. For fluid conditions that demand more robust solutions, opt for the SNT LIMIPHON control type, specifically engineered for extreme environments.
