Options
USTSII trap station
The trap contains an inverted bucket mechanism which responds to the
difference in density between steam and condensate. The discharge action
is cyclic. Condensate and non-condensibles are discharged close to steam
temperature. The UIB is designed to maintain the bucket in the proper plane
by means of a swivel connector. The trap is easily replaced without disturbing
the piping connections.
