Abstract
In a method for sterilizing a container, a valve body (30) is supported by a gas chamber (24) which is under atmospheric pressure. As a result when a pressure difference is present a static condition arises and keeps the valve open or closed. The valve can be used in a variety of way as influx or admission valve or condensate drain valve or as vacuum or condensate drain valve. The control method effects that in each phase the effective valve is kept open also after reaching the negative or positive peak pressure value until the pressure in the autoclave has adjusted itself to a predetermined closing switching pressure.
