The AOC-6843 series represents the pinnacle of our innovative cage guide control valves, boasting a significant Cv value and unparalleled dynamic stability. Designed to excel in a multitude of demanding heavy-duty services, this series is distinguished by its pressure-balanced trim, expertly crafted to handle high-pressure drops with ease. The AOC-6843L//D/E variants elevate this series further, integrating advanced multi-hole type cages specifically engineered to fulfill stringent low-noise and anti-cavitation criteria. These specialized cages replace standard ones, ensuring optimal performance while maintaining compatibility; all other components are fully interchangeable with the standard AOC-6843 series parts. For particularly challenging fluid conditions exceeding this series' capabilities, we recommend selecting the superior SNT LIMIPHON control type, engineered for the utmost efficiency and reliability.
