Description

Balanced pressure thermostatic steam traps are devices that sense the temperature difference between condensate and saturated steam.  These traps remain closed until the condensate collecting in the trap subcools enough to actuate the valve.  The amount of subcooling varies among designs, and is tailored to various applications ranging from biotechnology processing to apartment steam radiators.  Because these traps respond to temperature, they have excellent air venting characteristics.  Applications with quick or frequent start-ups perform best using balanced pressure thermostatic traps.

Watson McDaniel offers these traps in a wide variety of configurations and sizes to fit many applications.
