HWF2000B series 2-way motorized valve are designed to modulate the room temperature by controlling the flow of hot/chilled water in the central air-conditioner water system.
 

The valve is droved by in-phase motor and restored by a balance spring. It's normal-closed. When the thermostat sends out a signal of "open", the motor will drive the valve open. Then the chilled/hot water will go through pipeline coils (FCU) and cool/warm air will be distributed to the room by the operation of the fan. And when the temperature reaches to the setting point, the thermostat will send out a single of "close". The balance spring will restore the valve back to "close" position. Then the chilled/hot water supply will be cut off.
