Product Summary

Electric control valve actuators are used for the automation of industrial valves and can be found in all kinds of technical process plants: they are used in wastewater treatment plants, power plants and even refineries. This is where they play a major part in automating process control. The valves to be automated vary both in design and dimension. The diameters of the valves range from a few inches to a few meters.

Electric control valve actuators are the final control elements in an HVAC system. In chilled water systems, their function is to regulate the chilled water flow through the terminal units (air handling units or fan-coil). The control link to the valve is known as actuator. This device converts the controller’s output, such as an electric or pneumatic signal, into rotary or linear action required to move the valve stem through its operating range.

Electric control valve actuators may be considered as a variable orifice positioned by an electric actuator in response to impulses. They are made of materials best suited to the media handled, which in this case is water, and for dealing with the operating temperature and pressure. Therefore, internal parts such as seat ring, throttling plug or V-port skirt, disc holder, and stem, are sometimes made of stainless steel or other hard and corrosion-resistant metal for use in severe service. To correctly apply the different types of control valves used y chilled water systems, it is necessary to understand the internal construction of each valve.
