How to check fit and access
Check valve travel, clear tubes and vents and verify that technicians can reach the designated service points.
See inspection and acceptance checks →Steam & hot water
Control valve insulation jackets with service access
Insulate the valve body while keeping the actuator, tubing and instruments accessible.
Process heating, heat exchanger control and steam pressure stations.
Product views and construction details
Compare alternate views and see how the jacket opens, fits or fastens.
Design and specifications
Separating the body and instrument zones lets the cover be removed without disturbing control tubing.
- Shape and construction
- Multi-panel body cover with independent instrument access
- Facing, core and hot face
- Coated glass-fibre facing and fibrous core; confirm the hot-face fabric and fastening materials for the temperature at their actual locations.
- Nominal core thickness
- 25 / 40 mm nominal body options; reduce build-up near instruments only after review.
- Installation and closure
- Accessible straps or lacing; separate flap if the service points justify it.
- Dimensions to confirm
- Valve body envelope, actuator and stem travel, positioner, tubing routes, ports and service clearances.
These are options for a custom quotation. Confirm the assembled materials, dimensions, service limits and finish in writing.

Operating temperature and expected result
Review heat exposure at the actuator and instrument limits alongside body heat loss.
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.
