Heater valve control A21R23.8109030 for GAZELLE NEXT

The heater valve control is between the main engine tank and the warm air tank.

The heater valve is the warm air switch for the car heater. The car heater fan works on the principle that the radiator inside the heater fan is connected to the engine, circulating water through the inlet/outlet pipework, and the heater valve is the switch. When the heater valve is open, the water line is connected, the engine's circulating water enters the radiator, and the fan blows heat into the cab. Conversely, the heater valve closes, and the warm air does not work.
