Choosing the proper trap can make the steam heating equipment reach the highest working efficiency.In order to achieve the ideal effect, it is necessary to have a comprehensive understanding of the working performance and characteristics of various types of traps.
According to the different working principle of the trap, it can be changed into the following types: mechanical type: action depending on the change of the height of the condensate water in the valve.Thermostatic type: depending on the change of liquid temperature and action.Thermodynamic type: depending on the change of the thermal dynamic properties of the liquid and action.

  1. Can accurately exclude condensate water;
  2. No leakage of steam;
  3. Having the ability to exclude air;


Drain Valve Anti-freezing measures
