Operation

On initial start up the steam system, large amounts of cold condensate and air are present in the system. At this point the bimetallic strip of the delta element relaxes and fully opens the valve assembly to quickly expel the high volume of non-condensate gases and cold condensate through the discharge port.

As the element senses an increase in the condensate temperature the bimetal expands and raises the stem to modulate the flow. Just below the temperature of saturated steam the seat will close tightly to prevent live steam from discharging.

Application
