DQ320 motorized ball valve is always applied to control on/off of water system for water floor heating or heating of air-conditioning, it is consist of actuator and valve body . Actuator adopts the synchronous motor driver for its stable performance. Setting up the inner limited contacted points, which can make valve door power on or power off thoroughly when given or cut off the power .Valve body is casting with brass, nickel plated on the surface.

PS: Generally. The valve door will be set to be often- closed status originally, If you have any special request, pls let us know.

Temperature setting up dial: The pointer will be at the location of needed temperature

The Switch of system power on/ off: ON/OFF will be Power on/Power off
