NICHOLSON STEAM TRAP

THERMOSTATICSTEAM TRAPS

is the originator of the bellows actuatedThermostatic Steam Trap. s thermostaticproduct range spans applications from critical tracingto high capacity process. High sensitivity, immediateair venting and exceptional thermal efficiency are thehallmark of Thermostatic Steam Traps.


Operating PrincipleThermal actuator is filled at its free length with a liquidhaving a lower boiling point than water. On start-up,valve is normally open. When steam enters trap,thermal actuator fill vaporizes to a pressure higherthan line pressure. This forces valve into seat orificeto prevent any further flow. As condensate collects,it takes heat from thermal actuator, lowering internal

pressure. Line pressure will then compress thermal actuatorto open valve and discharge condensate. Valve openingautomatically adjusts to load conditions from minimum onvery light loads to full lift at maximum load. Restrictedorifice in N125L (small opening at bottom of valve seat)prevents trap from discharging continuously on light loads.

Operating PrincipleThermal actuator is filled at its free length with a liquidhaving a lower boiling point than water. On start-up,valve is normally open. When steam enters trap,thermal actuator fill vaporizes to a pressure higherthan line pressure. This forces valve into seat orificeto prevent any further flow. As condensate collects,

it takes heat from thermal actuator, lowering internalpressure. Line pressure will then compress thermal actuatorto open valve and discharge condensate. Valve openingautomatically adjusts to load conditions from minimum onvery light loads to full lift at maximum load.
