Temperature Control Ball Valve
WQF-SA
Product Description
WQF-SA series digital temperature control ball valve comes with temperature sensor (lower part of ball valve). In accordance with the water supply within the water pipe, the user can set the cooling and heating mode. In accordance with preset turn-on temperature and turn-off temperature, the temperature control ball valve will open or close the ball valve automatically.
Temperature sensor has been installed in the lower part of the ball valve, comes with 220VAC power plug, saving circuit installation time.
Optional relay without electricity normally opened and normally closed contact output, can synchronize the control of wall-hung boilers and other equipment.
Optional infrared remote control components, matching the remote control
Optional power failure self-reset function, the user can choose valve keep, open and closed, the temperature control ball valve running to the appropriate state when power failure.
