I worked at a shop and when we would put on tires and new valve stem we would first cut the inside off or at least sever it and then you screw on the puller to the valve and use the rim as a fulcrum and pull out the old valve stem. Then you should lube up the new valve stem stick it through the hole and attach the remover and pull it through till it snaps in place.
To deflate an inner tube properly, first locate the valve stem on the tube. Press down on the valve stem to release the air. You can use a tool like a valve core remover to help release the air more efficiently. Make sure to deflate the tube completely before removing it from the tire.

Unless one is a skilled mechanic, one should not use a tyre machine. One should have safety glasses, mounted tire and rim valve stem remover, valve core remover,a tire tool bar and tire lubricant before attempting to use a tyre machine.
To repair a bike tire valve stem, you can try tightening the valve core with a valve core tool or replacing the valve stem entirely. If the valve stem is damaged, it may need to be replaced by a professional bike mechanic.
To efficiently deflate a bike tire, first locate the valve stem on the tire. Press down on the small pin inside the valve stem to release the air. You can use a tool like a valve core remover for a quicker deflation process. Make sure to press down until all the air is released from the tire.
To properly deflate an inner tube, first locate the valve stem on the tube. Press down on the valve stem to release the air. You can use a tool like a valve core remover to help deflate the tube more quickly and completely. Make sure to remove all the air from the tube before storing or disposing of it.
You may be referring to the valve stem on each wheel.
Fit a new valve stem.
Yes, the gate valve is leaking at the stem.
Your bike tire may be leaking from the valve stem due to a damaged or improperly seated valve core, a loose valve stem, or a worn-out valve stem seal. This can cause air to escape from the tire, leading to a leak.
Bellow is similar to a hollow flexible hose. It functions like a vertical diaphragm (parallel instead of perpendicular to valve stem). It seals with the valve stem at one end, and seals with the valve body at the other end. Therefore, it allows a small relative move between valve stem and body, but prevents fluid from leaking across bellow surface. The move pushes seat or stem tip for valve to close or open. --SteveX
Your tubeless valve stem may be leaking air due to a damaged or improperly seated valve core, a loose valve stem nut, or a puncture in the valve stem itself. Inspect and address these issues to prevent further air leakage.
