Product Description
When a pipe is wrapped in thick insulation, the valve handle disappears under the lagging — you either cut a hole in the jacket or you can’t reach the valve at all. This ball valve stem extension solves it: a 304 stainless steel extension that lifts the operating lever 50–100 mm above the insulation layer, so the valve stays fully operable and the jacket stays intact.
It transmits torque solidly down to the ball, and it is used on steam, chilled water, and cryogenic lines alike.
Why Raise the Handle?
- Accessibility: the handle stays reachable and operable even under heavy insulation.
- Thermal protection: the operator’s hand stays away from the hot — or freezing — pipe surface.
- Insulation integrity: no need to cut large gaps in the lagging, so the system keeps its energy efficiency.
- Condensation prevention: on cold lines, the handle sits above the frost zone and stays dry.

Which Handle Do You Need?

|---|---|
| Extended handle (this page) | The valve sits under pipe insulation and the grip has to clear the jacket. |
| Lockable handle | The valve must be padlocked for lockout/tagout. |

Frequently Asked Questions
What is a ball valve stem extension?
An accessory that lengthens the valve stem and raises the operating handle above the pipe’s insulation layer. You keep full control of the valve without cutting a hole in the lagging.
How tall is the extension?
Typically 50 mm to 100 mm (about 2″ to 4″). Custom heights are available — tell us your insulation thickness and we will match it.
Which valves does it fit?
Our own ball valve series. The extension is made to match our valve stems, so we do not guarantee fit on other brands’ valves — include your valve model when ordering.
Does it work on cold and cryogenic lines?
Yes. On chilled-water and cryogenic lines it keeps the handle above the frost zone, so the grip stays dry and the operator’s hand stays off the freezing surface.
Do I have to cut the insulation to fit it?
No large openings are needed. The point of the extension is to keep the insulation jacket intact — the handle simply sits above it.
