Product Description

Product Description

Introducing the AOC-6840W Series Bellows Sealed Control Valve, a remarkable evolution in valve technology. This innovative product builds upon the robustness of our existing medium and low-pressure series control valves, integrating a sophisticated bellows seal structure. By preserving the original design attributes, while enhancing the upper cover with an advanced bellows seal, this valve ensures an impeccable seal, effectively preventing any risk of media leakage through the valve stem movement gap. As a result, the AOC-6840W Series is the ideal choice for control systems handling extremely toxic, corrosive, volatile, and highly penetrating media, as well as rare and valuable substances. Its unparalleled sealing capabilities make it indispensable in maintaining the integrity and safety of your operations.
