GMK Bimetal Steam Trap

When it comes to thermodynamics, a “bimetal” is a term that refers to two bonded plates of different metals. When subjected to a change in temperature, the dissimilar metals begin to deform because of the difference in the thermal expansion coefficients of the various metals. When it comes to bimetallic steam traps, the process of opening and closing a valve head is controlled by a deformed bimetallic element. Some bimetallic steam traps allow for the working temperature to be set by the user via programmable controls. The field technicians are able to alter the temperature at which the bimetallic steam traps it is running by using other varieties of the device. The bimetal element in these traps opens when the temperature falls below a certain threshold, and it shuts when the temperature exceeds a certain threshold.

  • The bimetallic steam trap offers a number of advantages, including its space-saving design and high level of durability in comparison to other steam traps.
  • A bimetallic steam trap allows for a respectable amount of airflow to be released into the environment.
  • This steam trap has a reasonable amount of resistance against Water Hammer’s effects.
  • The performance of bimetallic steam traps is satisfactory even when they are subjected to extremely high temperatures.
  • This trap is capable of reaching a fair degree of thermal efficiency when it is set up in such a way that it releases sub-cooled condensate. In steam traps made of bimetallic materials, an explosion caused by sub-cooled condensate is highly improbable.
  • Even in extremely cold situations, a bimetallic steam trap does not require further protection against freezing if its discharge is piped as a free draining line. This is the case even when the environment is extremely cold.


  • This type of steam trap is applied with a bimetal strip which expands with heat and contracts with cold in order to drain water and prevent steam
  • This steam trap is small in size and light in weight. With easy installation, it can be installed at any angle
  • The air and condensation water can be discharged rapidly during the initial operation of valves without any airlock situation
  • It is sensitive in induction and can be drain water without any noise, which is also very strong in resistance to corrosion
