Features: The electric three-way ball valve is suitable for the flow control of fan coil. Compact structure, the valve body is made of brass and the drive is powered by hysteresis synchronous motor Easy to control , the valve open by power on. After power off, the valve body is closed by itself and equipped with manual valve opening operating mechanism This motorized ball valve is mainly adopted of brass forging, reliable and durable. Ball valve and actuator for nut connection Installation, quick disassembly. Can be used in air conditioning system and plumbing systems.
