Valve Jackets – Insulation Blankets for Valves

Jun 16, 2025 | Shannon Blog

The Latest innovation in Energy Efficiency

How many times do we see articles in trade publications and social media excitedly describing new equipment installs for energy efficiency, and yet gate valves, pressure reducing valves, valves of all types, and fittings are left bare.

Photos of shiny new equipment are highlighted, alongside heat-wasting bare components.

The latest control software might tell you how your valves are functioning, but it won’t tell you if they are insulated properly.

What is important to know about heat loss

If you are seeing Bare valves, flanges and fittings in your steam system’s mechanical room, you are losing a large amount of energy.

Though these components may look like only a small part of your steam system, look again.  They have complex geometry and a lot of surface area.

How Much Heat Loss? How Much Energy?

Look at the Surface Area of a typical valve:

Four  6-inch 150# Gate valves has surface area = over 20 linear ft of 6-inch pipe.   That is a lot of uninsulated surface.  Multiply that by hundreds of valves in a system and you can understand how important it is to insulate.  A Shannon GES Energy Survey will  provide the details for your particular system.
