How to check fit and access
Check overlap along the curved panels, handwheel operation and access to the gland.
See inspection and acceptance checks →Steam & hot water
Removable globe valve insulation jackets
Fit the curved body without crowding the bonnet or packing gland.
Steam throttling stations and hot-water control loops.
Product views and construction details
Compare alternate views and see how the jacket opens, fits or fastens.
Design and specifications
Shaped panels follow the rounded valve body and let the gland remain available for adjustment.
- Shape and construction
- Contoured body panels with a formed bonnet opening
- Facing, core and hot face
- Coated glass-fibre outer and woven hot face with a needled glass-fibre or flexible mineral-fibre core.
- Nominal core thickness
- 25 / 40 mm nominal core comparison; check the thickest point around the bonnet.
- Installation and closure
- Overlapping textile tabs outside the hot face; use temperature-rated straps where required.
- Dimensions to confirm
- Widest body diameter, bonnet and packing-gland height, flange OD and clear space above the body.
These are options for a custom quotation. Confirm the assembled materials, dimensions, service limits and finish in writing.

Operating temperature and expected result
Compare heat loss from the covered body while documenting any bonnet surface left exposed.
Agree the conditions, measurement points and target for the proposed cover before quoting. Record the complete assembly’s approved service limits separately from the target outside-face temperature.

Calculated outside-face temperature for Shannon LT450SS at 21.1 °C ambient, flat-surface model. The manufacturer lists a maximum service temperature of 232 °C for this model. The columns show its nominal insulation thicknesses in millimeters and the manufacturer’s approximate inch equivalents.
| Operating temperature | 25 mm (1 in) | 40 mm (1½ in) | 50 mm (2 in) |
|---|---|---|---|
| 121 °C | 37.9 °C | 33.3 °C | 30.8 °C |
| 177 °C | 47.3 °C | 40.3 °C | 36.3 °C |
| 232 °C | 57.2 °C | 47.8 °C | 42.3 °C |
These figures describe the cited manufacturer’s model. Shape, airflow, compression, gaps and closures affect the installed result. A lower outside-face temperature still needs to be checked against your site’s contact and inspection requirements.
