Comparison:
Full heating jacket (type HM) and partial heating jacket (type TM)
Type HM (fully heating design)
heating from flange to flange, up to the cover seat
Type TM (partially heating design)
heating of the valve body (cost saving option)

Heating jacket plug valve with Oversize Flanges
Standard flange
Oversize flange
cast heating jacket (valve)
oversize flanges of the valve and pipe
heating jacket of the pipeline goes up to the pipeline flange (without thermal bridge)
Benefits of oversize flanges
- uninterrupted heating of pipeline and valve up to the flanges, without thermal bridge
