A chilled water valve actuator is a device used to control the flow of chilled water in a heating, ventilation, and air conditioning (HVAC) system. It is a motorized valve that is connected to a thermostat or other control system, and it is used to regulate the temperature of the air in a building. The actuator works by opening and closing the valve, allowing the chilled water to flow through the system. The actuator is designed to open and close the valve in response to changes in temperature, ensuring that the desired temperature is maintained. This type of valve is typically used in large commercial buildings, where precise temperature control is essential. It is also used in residential HVAC systems, where it helps to ensure that the desired temperature is maintained throughout the home. The chilled water valve actuator is an important component of any HVAC system, as it helps to ensure that the desired temperature is maintained, while also helping to conserve energy.
