GMK Thermodynamic Steam Trap

In order to function, thermodynamic steam traps use the peculiar dynamics of water and flash steam. They can withstand extreme heat and pressure while still functioning reliably and simply. When it comes to steam traps, the thermodynamic trap is one of the most reliable options available due to its strong design and straightforward functioning. The trap functions thanks to the dynamic impact of flash steam passing through the trap. The disc above the flat face inside the cap serves as the sole movable component. Cool condensate plus the air is quickly expelled from the inner ring, under the disc, and out via three peripheral outlets as soon as the disc is lifted by incoming pressure. The pressure of the hot condensate pouring via the inlet tube into the chamber under the disc lowers, releasing the flash steam, which travels at high speed. The disc is attracted to its resting place because of the low-pressure area created by its high speed.

  • Throughout their entire useful temperature range, thermodynamic traps can function with no modifications to their internals.
  • They are a great option because of their small footprint, ease of use, low weight, and high condensate capacity.
  • There is no effect of water hammer or vibration on thermodynamic traps, therefore you can use them with superheated steam under high pressure. Condensate corrosion is greatly reduced thanks to the sturdy stainless-steel design.
  • Thermodynamic traps are unaffected by freezing and are not likely to freeze if the disc is positioned in a vertical plane and the trap is discharged freely into the atmosphere. However, the disc edge could be damaged if it were to continue to operate in this orientation over time.
  • Since the disc is the only working portion, servicing the trap does not require taking it off the line.
  • Testing a trap is simple because you can hear it open and close with a simple “click.”


  • It has a steam or air thermal insulation device, which will not be affected by the environmental humidity. It reduces the frequency of motion and lengthens the lifetime
  • It is equipped with a filter and drain valve
  • It is sensitive and reliable in operation with a large capacity


Working principle

Thermodynamics steam trap works by moving valve block ups and downs. When the valve block is jacked up, the condensation water will be drained out. And when the steam gets into it, the valve block will close tightly.
