HVAC System DDF-J1 Electric Valve

 DDF-J1 is used to control the opening or closing of pipes in cold or hot water air conditioning systems to control room temperature. The driver is driven by a unidirectional hysteresis synchronous motor. The valve spring is reset. The valve is in a closed state when it is not working, when it needs to work, An open signal is provided by the thermostat to enable the driver to switch on the AC power and open the valve. Cold or hot water enters the fan coil to provide air conditioning or heating to the room. When the room temperature reaches the thermostat setting, The thermostat cuts off the opening current of the valve, and the reset spring closes the valve, thus cutting off the flow of water entering the fan coil. By closing and opening the valve, the room temperature always explodes within the temperature range set by the temperature control
