What is an Electric Actuated Ductile Iron Butterfly Valve Used For?
Electric actuated ductile iron lugged and tapped butterfly valves are utilised in various industrial applications requiring robust and secure flow control. The ductile iron construction provides superior strength and durability, making these valves suitable for higher pressure environments and demanding applications. The lugged and tapped design allows for easy installation and removal of the valve without disturbing the pipeline, facilitating maintenance and system isolation. These valves are ideal for use in water and wastewater treatment, chemical processing, HVAC systems, and industrial automation. The electric actuator enables precise, automated control, enhancing operational efficiency and allowing for remote operation.
Key Features
