Pneumatic Diaphragm Actuator Low Noise Guided Seated Globe Valves for Optimal Performance ANSI 150-2500 Body Rating

^{The AOC-6843 series represents the pinnacle of our cutting-edge cage guide control valves, boasting an impressive large Cv value alongside exceptional dynamic stability-perfectly engineered for a broad spectrum of heavy-duty services. These remarkable valves feature a pressure-balanced type trim, expertly designed to handle high-pressure drops with ease. The AOC-6843L//D/E series specifically introduces control valves that excel in meeting stringent low noise and anti-cavitation requirements. This is achieved by integrating advanced multi-hole type cages, which elevate performance beyond the standard cage design found in the traditional AOC-6843 series. Notably, all components, aside from the specialized multi-hole cage, are fully interchangeable with the original parts of the AOC-6843 series, offering unparalleled flexibility and convenience. For particularly challenging fluid conditions beyond the capabilities of this series, we recommend the advanced SNT LIMIPHON control type-your solution for severe conditions.}
