OPERATING PRINCIPLE

is based on the different density between steam and condensate. The weight of the float acting through the lever, keeps the valve closed when the trap is empty. As the condensate enters the trap it rises the float and opens the valve overcoming the pressure acting on it.If no more condensate reaches the trap the float descends closing the valve again. When the condensate load is steady the float sets to produce a continous discharge. The condensate
level in the body is always above the valve creating a perfect water seal. The closed float trap is unable to discharge air, herefore a small thermostatic air vent is always installed inside the body at this purpose.
