Wdv BK Series Bimetallic Steam Trap | Durable Thermostatic Steam Trap for Steam Main, Steam Tracing and Industrial Heating Systems
Product Spotlights
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.Simple structure,easy to install and maintain,resistant to water hammer and superb emptying performance.
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.
