Frequently Asked Questions

 

Which is the best steam trap design for drip leg applications?

The Velan multi-segmented design is the most efficient and longest lasting steam trap for drip leg applications on the market today.  Because of it’s constant modulation of condensate, you will see the following benefits:

  1. No live steam is lost during operation.
  2. Constant modulation reduces wear on internal parts, producing a much longer service life.
  3. Discharging condensate 20°F below saturation temperature will lower back pressure in closed return systems because of less flash steam.

 

Thermodynamic designed steam traps discharge condensate in a blast-on / blast-off mode of operation.  This design also discharges condensate at steam temperature.  Because of this, customers that use this design have to do the following:

  1. Generate more steam to compensate for losses due to high cycling.
  2. Replace steam traps more frequently because of constant cycling.
  3. Deal with elevated back pressure in the return system because of flash steam.

 

Inverted bucket designed steam traps discharge condensate in a blast-on / blast-off operation.  This design also discharges condensate at steam temperature.  Because of this, customers that use this design have to do the following:

  1. Generate more steam than needed due to "lost" steam out the "weep" hole.
  2. Replace steam traps more frequently because of constant cycling.
  3. Deal with elevated back pressure in the return system because of flash steam.
