Cast Steel And Stainless Steel Flanged Free Ball Floating Steam
Trap With Auto Air Vent Function
Product introduction:
Free ball floating steam trap valve products use the principle of
buoyancy, float according to the amount of condensed water changes
with the water level and rise, automatically adjust the opening of
the valve seat hole, continuous discharge of condensed water.When
the condensate stops entering, the float drops to the bottom by its
own weight and closes the drain seat hole.Because the drainage
valve seat hole is below the condensate water level, the water
vapor is separated naturally and the water seal is formed to
achieve no steam leakage.

Product application:
Used in steam heating equipment, condensate recovery system and
conditions requiring rapid condensate discharge, it can
automatically, rapidly and continuously discharge condensate,
effectively prevent steam leakage, and obtain the best heating
effect.
Product advantages:
1. Simple structure and long lifespan: There is only one movable
component inside - a finely ground stainless steel hollow floating
ball, with no vulnerable parts and a long service life.
2. Continuous drainage, stable performance: It can automatically
adjust the opening of the valve seat hole, continuously discharge
condensed water without being affected by pressure, temperature,
and fluctuations in condensed water flow rate. The minimum
subcooling degree is 0 ℃, and there is no water accumulation in the
heating equipment, resulting in high thermal efficiency.
3. Good automatic air exhaust performance: Built in automatic air
exhaust device can sensitively eliminate air or non condensable
gases in the pipeline, prevent air lock phenomenon, and ensure
rapid heating of the equipment.
4. Superior sealing performance: The floating ball has high
precision, good sealing performance, low steam leakage rate, and
significant energy-saving effect.
5. Widely applicable: It can be used for steam heating equipment
and steam pipelines in industrial sectors such as petroleum,
chemical, light industry, metallurgy, and power, especially
suitable for drum drying equipment with high requirements.
6. Easy maintenance: The internal parts are easy to disassemble,
making it convenient for inspection and maintenance.
7. Good water hammer resistance: It can effectively prevent water
hammer phenomenon and protect the safe operation of pipelines and
equipment.
These advantages make automatic free floating ball drain valves
play an important role in industrial steam systems, ensuring stable
operation of steam heating equipment and pipelines, improving
thermal efficiency, and saving energy.
