UIB30 and UIB30H Sealed Inverted Bucket Steam Trap
(for use with Universal Connectors)
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.

Sample Specification
Steam trap shall be supplied with a pipe-
line connector which, once installed,
remains in the pipeline permanently. Trap
shall be attached to the connector by two
bolts to enable simple and rapid instal-
lation and replacement. The connection
is designed to allow installation on pipe-
work that is vertical, horizontal, or any
angle in between. The trap itself shall be
inverted bucket type of all-stainles steel
construction which resists distortion due
to freeze-up and waterhammer. Trap to
have a forged body and drawn cover fully
weld-sealed against leakage. Operation
shall be self-priming, with orifice size
selected for the capacity required by the
application, and suitable for working pres-
sures to 435 psig.
Installation
The connector can be installed in hori-
zontal or vertical lines. The connector
face must be in a vertical plane. The trap
should be fitted to the connector with the
body pointing downward. Full-port isolat-
ing valves should be installed upstream
and downstream of the connector.
Maintenance
The trap can be removed for repair or
replacement without disturbing the con-
nector piping connections. Complete iso-
lation of the connector from both the sup-
ply and return lines is required before the
trap is removed. Complete installation
and maintenance instructions are given
in the IMI sheet, which accompanies
the product.

Available spare parts are shown in
