How do I remove this valve?

I've got to get inside the tube (ref this thread) and was hoping the centre of the valve would unscrew like a car tyre, but not so.

The centre valve part and the surround all appear to be one piece. It's on a Ribeye 500. Any ideas?

thanks,

Alex

You will need a spanner which is provided by the manufacturer. They can be a pian in the arse!

The Halkey-Roberts valve body (which you see on the outside) is one piece. Inside the tube, there is a threaded collar that spins onto the body, trapping the fabric between the two flared portions, which makes the seal.

To remove the valve, you need to unscrew the inner collar (or if you look at it the other way, unscrew the body from the inner collar.)

The first pic shows the complete valve without the tube in the way. The second pic shows one style of valve wrench available.

Thanks all!

The obvious concern now, assuming I can loosen it, is the nut/collar falling off the back and into the tube! Presumably I'll have to try to hold the nut through the fabric from the other side somehow?

if you dont have a spanner you can hold the back of the valve through the tube and very carefully use the prongs of a set of long nose pliers to undo the valve ,it is best to have oneperson hold the valve and another use the pliers to undo it

Yep.. Use the special spanner( only a few quid)... With the tube fully deflated squeeze the tube together to support the inner part of the valve.. When I was removing mine I used a wire coat hanger.. Bend the end into a small hook and put it down the middle of the valve.. When you screw off the top bit the inside part won't fall into the inside of the tube as youll have it hooked! That happened to me once so I learned by my mistake !!  ...best of luck with it..
