Spirax Sarco Steam Trap, Universal Bi-Metal, 300 psig, Stainless Steel, 18 deg F

The USM21 is a pre-set and maintenance free sealed bimetallic steam trap manufactured in stainless steel. It is designed for steam pressures up to 21 bar and applications such as steam tracing and mains drips. When installed in any position with a suitable pipeline connector the USM21 can easily and simply be removed without breaking into the pipeline, thus speeding up trap replacement with minimal system downtime.

Except for start-up and shutdown, Spirax Sarco 6250253, which has a nominal subcooled temperature of -18°F (-10°C), must operate above the minimum differential pressure values of 73 psig (5 bar g).
