Globe valves are one of the most common types of valves in industrial systems, playing an essential role in regulating and controlling the flow of steam, hot water, thermal oil, and more. However, with their characteristic spherical body structure, they are also one of the most significant points of heat loss on a pipeline, while also posing a safety risk if not properly covered.

Challenges in Insulating Globe Valves

Insulating globe valves using traditional methods often encounters many inherent difficulties due to their shape and operational requirements:

Bulbous, Non-Uniform Shape: The large, spherical body and the raised bonnet create a complex geometry. Using rigid materials to cover them makes it very difficult to achieve a snug fit, invariably leaving gaps that cause heat loss.
Large Heat-Radiating Surface Area: Compared to a straight section of pipe of the same length, the surface area of a globe valve is significantly larger. This turns it into a concentrated “hot spot” that continuously radiates energy into the environment.
Difficult Maintenance Access: The valve bonnet contains the packing, which needs to be periodically tightened or replaced to prevent leaks. With fixed insulation, accessing the bonnet bolts is impossible without destroying the insulation layer.
Heat Transfer to the Handwheel, Posing a Danger: In high-temperature applications, heat can travel up the valve stem to the handwheel, causing it to heat up, which makes operation difficult and dangerous for personnel.

The Optimal Solution: Custom-Fitted Insulation Jackets for Globe Valves

The custom-fitted insulation jacket solution is designed to completely conquer the challenges of globe valves, delivering superior performance in both energy savings and operation.

A Design that Envelops the Valve Body, Eliminating Heat Loss: Each jacket is 3D-fabricated to the exact model and size of the globe valve, ensuring it snugly fits and envelops the entire valve body and bonnet, leaving no space for thermal energy to escape.
Reduced Surface Temperature, Safe Operation: The insulation jacket immediately lowers the valve’s surface temperature to a safe-to-touch level. This not only completely eliminates the risk of burns but also significantly reduces the heat transferred to the handwheel, making valve operation safer than ever.
Flexible Removal and Reinstallation in Minutes: When the bonnet or packing requires maintenance, an operator can easily remove and reinstall the insulation jacket quickly thanks to a smart system of straps and buckles. Maintenance becomes simple and no longer requires costly re-insulation work.
Noticeable Energy Savings: Effectively insulating numerous globe valves in a plant will significantly minimize heat loss system-wide, thereby reducing the load on boilers and directly cutting fuel costs.
Durable and Professional: Using high-grade materials resistant to heat and industrial environments, globe valve insulation jackets provide a sustainable, long-term solution and create a tidy, professional appearance for the plant.

Insulating globe valves is not just something that should be done; it is a necessary step in any energy conservation program. It is a small investment that yields a quick and sustainable return.
