Introducing the remarkable AOC-6843 series, our latest innovation in cage guide control valves designed to deliver unparalleled performance and reliability. With a substantial Cv value and exceptional dynamic stability, these valves are engineered to excel in various heavy-duty applications. This advanced series boasts a pressure-balanced trim, expertly crafted to handle high-pressure drops with ease. Elevate your system's performance with the AOC-6843L//D/E series, featuring cutting-edge control valves tailored for low noise and anti-cavitation needs. By integrating multi-hole type cages, instead of the standard cages found in the AOC-6843 series, we ensure superior noise reduction and cavitation resistance. All components, save for the multi-hole cage, are fully interchangeable with those from the AOC-6843 series, offering flexibility and convenience. For the most demanding fluid conditions beyond this series' capabilities, we recommend selecting the SNT LIMIPHON control type for optimal results.
