About products
Introducing our latest innovation, the AOC-6843 series, a cutting-edge cage guide control valve designed to deliver exceptional performance with a large Cv value and outstanding dynamic stability. Perfectly engineered for a wide range of heavy-duty applications, this series is distinguished by its pressure balanced trim, ensuring optimal functionality even at high pressure drops. The AOC-6843L//D/E series advances this innovation further by integrating multi-hole type cages, specifically crafted to meet the stringent demands of low noise and anti-cavitation, setting it apart from standard cages in the AOC-6843 lineup. Remarkably, all components, excluding the multi-hole cage, are fully interchangeable with the AOC-6843 series components, offering versatility and convenience. For fluid conditions that extend beyond the capabilities of this series, our elite SNT LIMIPHON control type is recommended for superior performance.
