The AK 45 automatic drainage valve rapidly and automatically discharges air and condensate from steam systems on start-up and drains residual fluid when the system is shut down.
The integrated spring enables the AK 45 to open without pressure.
The valve closes as soon as the operating pressure increases to the closing pressure set. If the operating pressure falls below the closing pressure once more, the AK 45 is opened by a spring force and drains residual fluid preventing the formation of a vacuum.
