About products
Introducing the AOC-6843 series, our state-of-the-art cage guide control valve designed with a large Cv value and exceptional dynamic stability. Engineered for a wide variety of demanding heavy-duty applications, this series is equipped with a pressure-balanced trim to handle high-pressure drops with ease. The AOC-6843L//D/E series further enhances performance by meeting low noise and anti-cavitation needs through the innovative use of multi-hole type cages, a significant upgrade from the standard design. Notably, all components, excluding the multi-hole cage, are interchangeable with the standard AOC-6843 series parts, ensuring seamless integration and versatility. For even more challenging fluid conditions that surpass the capabilities of this series, we recommend opting for the advanced SNT LIMIPHON control type for optimal results.
