The thermo-sensitive element of bimetallic trap is a bimetallic element cast through a special process by two metals of different expansion ratio. When the bimetallic element expands after heated, different expansion ratio results in bending. The thermo-sensitive element produced on the basis of this quality can act as a switch. Bimetallic Traps are divided into adjustable offline (BK, CS17H and CS47) and online (adjustable bimetallic element TB).

2. Water seal by high-temperature condensate, no leakage of fresh steam (zero leakage).
3. Flexible and noiseless.
4. Water hammer resistance with no effect from abrupt pressure changes.
5. Adoptable for overheat steam system.
6. Adoptable for high-pressure and high-temperature steam pipes.

7. Good air discharge quality with resistance to coldness.
