The CI 5-9 01 24V AC part is a proportional solenoid valve actuator, manufactured by Danfoss, that is designed to control the proportion of the pressure and flow of a liquid medium in an industrial environment. It is an electronically controlled, proportional valve actuator that uses a 24V AC powering source, providing an adjustable pressure relief function, with a direct-acting principle, allowing for smooth and precise control of both pressure and flow of liquid media, such as water and oil, within a system. The CI 5-9 can be used in a wide range of applications, such as in the food, beverage and dairy industry. The actuator is designed with compatibility in mind, able to work with all currently known valve manufacturers, making it an ideal choice for retrofitting existing valves without coding. It also comes with a built-in diagnostic system, allowing for easy maintenance and troubleshooting.
