    Abstract: For sealing off overpressure valves of packaging containers, a small quantity of liquid sealant is introduced into a valve. To check whether such valve has been equipped with sealant, the sealant is heated, prior to introduction into the valve, to a temperature that is elevated compared with ambient temperature. After that the valve is checked for a temperature difference with a heat sensor, which causes valves not equipped with sealant to be rejected. The sealant is heated immediately prior to its application to a valve, in a nozzle delivering it.
