Frequently Asked Questions
What measurements do you need for a butterfly-valve stem extension?
Provide the valve position, distance to the intended operating point and available route and clearance for the extension. Ask for an assembly drawing showing the required supports and operating arrangement.
Can I use one of the example extension lengths without an installation review?
Confirm the required length and arrangement for your actual installation. The examples on the page do not replace a review of the selected valve, operating mechanism, support arrangement and access conditions.
What should I check if the operating point is above an underground valve?
Show the proposed valve orientation and ground-level operating position on the inquiry drawing. Request confirmation of the extension alignment, access and maintenance requirements before fixing the layout.
