Conbraco Industries 27-202-02 Radiator Air Valve

The Conbraco Industries 27-202-02 Radiator Air Valve automatically releases the trapped air in the hydronic heating and cooling circuits to ensure the efficient flow of fluids and heat exchange in HVAC systems. It works based on a float-controlled system, which opens a vent when the air builds up and closes when the liquid rises. It is mounted on the radiator, and piping runs at high locations and is then connected to the system by threaded fittings to control the separation of air.
