SR06 Series FCU Valves

SR06 Series FCU Valves

SR06 series motorized valve is used to control the flow of the pipe in chilled/hot water system so as to control the room temperature. DC motor in motorized valve is driven by on-off power module and automatically returned after power off. When motorized valve does not work, it is normally closed. When it works, the room thermostat sends a signal to the motorized valve to open. Then the Chilled / hot water enter into fan coil unit so as to supply the cooling or heating to the room. When room temperature meets the set point of thermostat, the thermostat will send a signal to close the motorized valve. Through the control of the opening of the valve, the room temperature maintains within the set range of the thermostat.
