UBP32

Sealed Balanced Pressure

Thermostatic Steam Trap for use with Pipeline Connectors

Description

The UBP32 is a maintenance free sealed balanced pressure

steam trap manufactured in stainless steel - It can also be

supplied with an inbuilt check valve designated UBP32CV.

When installed with a suitable pipeline connector the UBP32 can

easily and simply be removed without breaking into the pipeline

thus speeding up trap replacement with minimal system downtime.

Pipeline connectors are available with screwed, socket weld

and flanged connections.

Capsule operation

As standard the UBP32 is supplied with a thermostatic capsule

(STD) which operates approximately 12°C below steam saturation

temperature. It can also be supplied with capsules operating near

to steam 4°C below (NTS) or sub cooled 22°C below (SUB).

Standards

This product fully complies with the requirements of the European

Pressure Equipment Directive 97/23/EC.

The body to cover welded joint complies with ASME Section IX

and BS/EN 288.

Certification

This product is available with certification to EN 10204 3.1.

Note: All certification/inspection requirements must be stated at

the time of order placement.
