Description
Thermostatic/thermodynamic steam trap with corrosion resistant Thermovit®? regulator (S. S. bimetallic plates) able to with?
stand waterhammer. With internal strainer and integral non-return valve action. Asbestos-free body gasket (graphite/CrNi).
Installation in any position.
The default factory setting enables the steam trap to discharge condensate with virtually no banking-up.
Function
During start-up of the plant the bimetallic (Duo stainless steel) plates are flat. The service pressure acts in the opening
direction, the valve is completely open. As the condensate temperature rises, the bimetallic plates deflect, drawing the stage
nozzle towards the closed position.
As the condensate temperature sinks, the deflection of the Duo stainless steel plates decreases and the steam trap opens
at the adjusted opening temperature.
The thermostatic and spring characteristics of the stack of plates are balanced such that condensate is always discharged
at a given undercooling temperature.
The steam trap provides automatic air-venting at start-up and during operation of the plant. BK 212 can also be used for
thermal air-venting in steam systems.
