Product Description
Product Description
The AOC-6841 top-guided control valves are ingeniously compact and boast a straightforward structure, perfectly suited for a wide range of applications. These valves excel in all cavitation-free liquid services and in steam and gas services that adhere to stringent noise regulations. With a focus on enhanced durability and simplified maintenance, the AOC-6841/2 trim is meticulously designed as a cage-guided trim, ensuring superior performance without the need for optional features.
The sleeve-guided heavy-duty single-seat control valve is engineered with a remarkable quick-release structure for its internal components. This innovative design not only enables the valve to endure higher pressure differences but also transforms on-site maintenance into a remarkably effortless task, making it an ideal choice for demanding environments.
