Steam Pipeline use Auto Cast Steel ASTM A216-WCB Level Ball Float
Steam Trap
Product introduction:
The lever ball float steam trap valve is an automatic valve type
mainly used in steam pipelines and equipment. It can automatically
discharge condensed water, air, and other non condensable gases,
and prevent steam leakage.
Level ball float steam trap's working principle is based on the
ball float rising and falling with the change of condensate water
level, thereby driving the lever to adjust the opening of the valve
seat hole and control the discharge of condensate water.
The lever ball float steam trap valve contains a movable float
inside, which floats up and down with the change of liquid position
in the valve chamber, and drives the opening or closing of the
valve disc through the lever mechanism.
-The valve seat is always below the liquid level, forming a water
seal to ensure no steam leakage.
-Internally equipped with exhaust devices, such as membrane box
components, which can automatically eliminate non condensable
gases, improving work quality and service life.

| Remark | The working pressure difference of the steam valve is selected
based on the actual working pressure difference of the user. The
actual working pressure difference must be lower than the maximum
working pressure difference of the steam valve, such as 0.1 bar-4.5
bar, 4.5 bar chosen, 4.6 bar-10bar, and 10 bar chosen. |
Product features:
-Continuous drainage: Level ball float steam trap is not affected
by pressure, temperature, or fluctuations in condensate flow rate,
it can continuously drain water as soon as there is water, enabling
the heating equipment to achieve optimal working efficiency.
-Good sealing performance: Level ball float steam trap valve seat
is always below the liquid level, forming a water seal with no
steam leakage and good energy-saving effect.
-Wide applicability: Level ball float steam trap is suitable for
various industrial steam heating equipment, especially performing
well in working environments with high condensate water
displacement.
-Automatic exhaust: Level ball float steam trap is equipped with an
automatic exhaust device inside, it can effectively eliminate non
condensable hot and cold gases and prevent air lock phenomenon.
-Long service life: Level ball float steam trap with special
sealing element which adopts a spherical structure without
concentrated wear during operation, special design of a balanced
double valve seat structure optional, which can achieve small
volume and large drainage capacity, and has a long service life.
-Low working pressure: Level ball float steam trap minimum working
pressure can reach 0.01Mpa, and the maximum back pressure rate is ≤
85%.
In summary, imported lever floating ball drain valves play an
important role in steam heating systems due to their excellent
performance and wide application range.
