SEV2000 ... ... the series of split electrically operated valves are composed of the SE20 series of valve drivers and the VE2, VE3 series of copper valves. It is used to control the open and close of the air-conditioning duct in charge of cold or hot water so as to control the room temperature and adjust Kv value. The driver is driven by one-way hysteresis synchronous motor and valve returning spring. When the valve does not run, it is in a normally closed state; when it runs, the thermostat sends a signal for turning on so that the AC power can be connected to drive the electrically operated valve. When the valve is open, the chilled water or hot water gets into the fan coil to provide cool air or warm air for the room. When the room temperature reaches the setting value of the thermostat, the thermostat will cut electricity off from the electrically operated valve, and the returning spring will close the valve so as to prevent water flowing into fan coil. Through turning on or off the valve, the room temperature can always be maintained into the thermostat range.
