Features: 1. Constant temperature heat dissipation valve is a special valve used in conjunction with the heating heat sink. 2. Flow rates through the heat sink can be adjusted without external hot water to achieve a constant ambient temperature. 3. It is suitable for electric drive parts of electric heating actuators for diverter valves, small valves and dynamic balancing valves. 4. The nut connection installation method is simple and quick to install and easy to disassemble. Use the water valve directly instead of installing the actuator and temperature control valve. 5. For Zigbee, the wireless hub is an indispensable device connected to the valve, and various for Zigbee products, it is the home control center.
