    Steam connection is used for the steam supply to pressurize the deaerator to the desired operating pressure (5-15 psig). The steam supply should have a pressure-reducing valve installed in the steam line, reducing the pressure to the proper operating pressure. The relief valves will also be mounted in the steam supply line.
