About products
AOC-6843 series is our latest cage guide control valve of large Cv value, and of dynamic stability. It is suitable to a variety of heavy duty services. This series is characterized by pressure balanced type trim for high pressure drops. AOC-6843L//D/E series provides control valves that meet low noise and anti-cavitation requirements by incorporating a multi-hole type cages, instead of the standard cages, in the AOC-6843 series cage guided control valves. All the parts except the multi-hole cage are interchangeable with the parts of the AOC-6843 series accordingly. For those severe fluid conditions that cannot be covered by this series, please select SNT LIMIPHON control type.
