NICHOLSON / Emerson – DS100 DS110 DS Series Steam Trap

The Thermal actuator is filled at its free length with a liquid that has a lower boiling point than water. On start-up, the valve is normally open to discharge air, non-condensibles and condensate.

The temperature difference is called sub-cool and is an indication of the sensitivity of the thermal actuator.

When steam enters the trap, the thermal actuator fill vaporizes at a pressure higher than line pressure. This forces the valve into the seat orifice to prevent any further flow.

As condensate collects, it takes heat from the actuator, lowering internal pressure. The line pressure will then compress the thermal actuator to open the valve and discharge the condensate. The valve opening automatically adjusts to load conditions, from minimum on very light loads to full lift at maximum load.
for vertical installation.

The Romynox model DS, with the economic line developed by Nicholson, has a 5 oC sub-cool. This steam trap is guaranteed to function without problems for 2 years.
The DS series is fully in line with the ASME BPE specifications.

The DS-serie is complete ASME-BPE. Two-year guarantee.
