System description
The UBK 46 is a steam trap with adjustable condensate discharge temperature, thereby suppressing
the formation of flash steam.
Main field of application: Steam heated tracing systems.
Design: With corrosion-resistant Duo stainless steel (bimetallic) regulator unaffected by waterhammer
and Y-type large-surface strainer.
Installation in any position. When installed in horizontal lines cover must be on top.
During start-up of the plant the Duo stainless steel plates are flat. The service pressure acts in the
opening direction, the valve is completely open. With rising condensate temperature the plates deflect
and draw the stage nozzle towards the closed position.
As the condensate temperature falls the deflection of the Duo stainless steel plates decreases and the
steam trap opens at the adjusted opening temperature.
Thermostatic and spring characteristics of the stack of stainless steel plates are balanced so that the
condensate is discharged without any flashing and at a constant temperature.
