Operating Pressure Range: 0.5 to 40 barg

Operating Temperature Range: 0 to 400 oC

Capacity Range: Up to 600 kg/h


Advantages of Float Traps:

  • Resistance to water hammer.

  • Corrosion resistance.

  • Resistance against the dirt of steam because of inbuilt strainer in the bucket.


  • Can’t sustain in low-temperature area, can freeze in a cold environment.

  • Possibility of steam leakage with low load.
  • The higher temperature of superheated steam can be a cause of losing traps water seal.
