3. Operation
1.
At start-up, since the float is down, the valve is closed.
In this state, air in the system and piping is discharged
out through the air vent which is opened. When
condensate flows into the product, the float lifts up
and opens the valve, and then discharges
condensate. Air is continuously discharged out from
the air vent.
When steam flows into the product, internal pressure
of the air vent rises by steam temperature, and the air
vent closes. According to the amount of condensate
inflow, the float position moves up and down changing
the opening degree of the valve, and thus condensate
is continuously discharged. The float moves down
and the valve closes when condensate inflow stops.
When air or non-condensable gas flows into the
product, it accumulates in the upper part of the
product. When temperature of air or non-
condensable gas decreases with condensate
inflow, the air vent opens and discharges it to
outside of the product.
Then, operations 2 and 3 repeats according to the
inflow amount of condensate and air.

4. Maximum Continuous Discharge Capacity
1. Discharging capability of the steam trap differs by working differential pressure, that is, difference
between inlet pressure and outlet pressure (back pressure). In selecting discharge capacity,
consider outlet pressure. If inlet pressure is 0.5 MPa and outlet pressure is 0.2 MPa, discharge
capacity is of working differential pressure of 0.3 MPa.
2. The discharge capacity shown in the charts below is the maximum value. In designing a system, select a
steam trap with a sufficient safety factor (two times the regular level). That is, for example, if a discharge
capacity of 500 kg/h is required, select a steam trap capable of discharging more than 1,000 kg/h (maximum
discharge).
