Removable gate valve insulation jackets
Cover the valve body and keep the rising stem and handwheel free to travel.
Split body and optional separate bonnet section
Specifications and thermal reference →Custom removable insulation
Custom jackets for valves, flanges and process equipment. Review the fit, cover layers and removal path around the equipment your team needs to service.
One-piece inquiries welcome. Send a drawing or a photo with scale to start a fit review.

Specifications and thermal reference →Review fit before committing to a cover
Send equipment dimensions or photos with scale. Once the key measurements are available, we can prepare a CAD drawing or an annotated design for both teams to review. Use it to agree which surfaces to cover, what must remain accessible and how the cover comes off.

How much insulation do you need?
Start with the equipment surface temperature and the result you need. Compare published thickness and outer-surface examples for steam, washdown and extruders. For chilled water, start with ambient humidity and dew point.
Compare thermal results →Example · steam service
At 177 °C operating temperature and 21.1 °C ambient, Shannon’s flat-surface model estimates 47.3 °C outside-face temperature at 25 mm and 36.3 °C at 50 mm for its LT450SS jacket.

Third-party project · Thermaxx Jackets
Restoring removable insulation in a campus steam network
Vermont, United States
Several steam components in a university mechanical room had been left bare after maintenance. The university wanted to reduce heat loss while retaining access to frequently serviced equipment.

A removable jacket for an outdoor brewery steam valve
New York, United States
The brewery wanted to protect a 6-inch gate valve on an outdoor high-pressure steam line while keeping a removable cover for service.
Read the project note →Illustrative design scenario
A flange cover that can come out sideways
A flange sits close to a wall and an overhead tray. The buyer can reach the bolts from one side but cannot lift a conventional full-depth cover vertically.
Read the project note →Show us the part that is hard to cover.
Send a drawing or a scaled photo. Mark anything the cover must clear and tell us how your team services the equipment.
Send your requirements →- Review fit and access. Start with the envelope, service clearances and removal path.
- Compare constructions. Discuss facing, core, seams and closure options for the duty.
- Agree what to check. Confirm the drawing revision, inspection scope and commercial terms before ordering.
