Thermodynamic Steam Traps with Swivel Connector
UTD30L shown fitted to a PC10HP connector
Description
The UTD30 series are stainless steel thermodynamic steam traps
with integral strainer having an electroless nickel preparation finish
(ELNP) which is both energy efficient and corrosion resistant. They
are attached to a suitable pipeline connector by two bolts for quick
and easy replacement.
