The AK45 Automatic drain valve can quickly and automatically discharge the air and condensate in the steam system when it is started and the residual liquid when the system is closed.

Integrated springs allow the AK45 to open without pressure.

The valve will close when the working pressure increases to the closing pressure set value. If the operating pressure again falls below the closing pressure, the AK45 will be opened by spring force, draining the residual fluid and preventing the formation of a vacuum.
