FCU Electric Ball valve(DN15-DN32)

The Series SFD Electric Two-way or Three-way Valve is designed for FCU cooling or heating pipes. Through opening and closing the pipe, the valve can effectively regulate the room temperature. 

-Good waterproof and anti-dust function(IP65)
-High pressure difference of valve and low leakage
-Flexible opening to avoid water hammer effectively
-The fluid road of valve is  advanced design, reduce the congestion phenomenon
-Actuator can be both sides to assembles, easy to wiring and maintain
-Don’t take anymore pressure after valve run in place, and owning longer life
-Easy to install without special tools
-The valve body can be used by manual manipulation
-Actuator can suitable for all ball valve(DN15-DN32)
-According to the eccentric construction of actuator, valve is installed stick to wall
-Dismounting simple, it can reloaded after install equipment and pipeline to improve work efficiency
-The temperature of the medium is not easy to transfer to the actuator
Operating Principles:

Electric Ball valve is on-off control valve used in the heating or cooling water systems. It can accurately control the flow of cool/heat medium depending upon the requirements of the given application, and can not result in sudden change of temperature and to control the room temperature accurately. when it need to work, the thermostat  provide a signal to the valve, actuator slowly open, so that let chilled water or hot water into the fan coil unit, to provide cooling capacity or heat capacity for the room; when the room temperature reaches the thermostat set value, Electric Ball valve received the signal and closes slowly, cutting water into the fan coil unit, reduce cooling capacity or heat capacity for the room.
