Description
Thermostatic/thermodynamic steam trap with corrosion resistant Thermovit® regulator (bimetallic plates) able to
withstand 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 steam trap is completely open. Cold condensate and air are discharged.
As the temperature rises, the bimetallic plates deflect, drawing the stage nozzle towards the closed position.
Just before the condensate reaches saturated steam temperature the orifice will be shut off tight. The thermodynamic effect
of the stage nozzle chamber assists in the closing process.
The steam trap provides automatic air-venting at start-up and during operation of the plant. BK 37..., BK 28... and
BK 29... can also be used for thermal air-venting.
