Replaces hand-operated or separately operated valves on start-up

The AK 45 rapidly and automatically discharges air and condensate from steam systems on start-up and drains residual fluid when the system is stopped. It is also used for frost protection. 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 for the AK 45. When the operating pressure falls below closing pressure once more, the AK 45 is opened by spring force and drains residual fluid, preventing the formation of a vacuum.
