Bimetallic Trap With Adjustable Temperature TB21
Overview
Bimetallic Trap
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).
Merits
1.Discharge temperature adjustable online by free installation posture.
2.High-temperature condensate water used to form water seal so as to effectively reduce steam leakage.
3.Flexible and noiseless,water hammer resistant,and good emptying performance.
4.Simple structure,easy to maintain and repair.
5.Adoptable for steam main pipes,gas distribution cylinders,steam tracing pipes,radiators,low-temperature heating trough,double layered pots and so on.
6.Adoptable for high-temperature steam pipes,gas distribution cylinders and so on.
Performance
Capable of adjusting the discharge temperature of condensate water so as to make effective use of its sensible heat.
Existing condensate water in front of the valve to form water seal to prevent steam leakage.
Capable of installation in any direction and water discharge temperature adjustable at any time.
Long durability thanks to washing and corrosion resistant alloy sphere valve core and stainless valve seat.

Note
1.Please provide operating pressure and operating pressure difference,generating quantity of condensate water,operating temperature,connecting mode and standards in selecting product models.
2.The load of condensate Water's safety coefficient reaches 2 to 3 times in general.
3.Please make sure the drain valve is installed properly,maintained regularly,cleaned up and operates under the normal condition,so as to extend its service life.
4.TB3 and TB5 same,TB6 and TB11 same.
