Clack Valve required
Hi Guys, I'm looking for a little help. I bought a pair of these, but a longish while ago, probably at a Bristol Show, the problem is I can't remember who from. It probably wasn't painted when I got it, I don't remember that either (getting old?). The pipe thread is 9/32" X 32ME, the fitting thread is 1/4" BSP, the Pound coin is to give a clue to the size. The only identifying mark I can find is a 'C' stamped on the top of the square.

I need another! This one wouldn't hold kitty, let alone water or steam, even though brand new. Can anyone in 7 1/4" land identify the source accurately, or I could spend a lot of time and effort chasing round. My other option of course is to wait for an exhibition and hope to bump into them there.

Thanks in anticipation,

Bob Gray.

Bob,

I have use something like these and I think I bought them from Geoff Stait at G&S Supplies but it was a while ago but worth a try but it does look as if they are just standard clacks anyway.
To stop it leaking have you tried a Nitrile ball in it ?

Denis, you could be right. I also thought possibly LSM.

Edit: - I've just checked Geoff's site and he doesn't seem to do one that big

It looks LSM or RA Barker, being 1/4 BSP. I was stupid enough to try a pair of such 'model engineer' clacks once, awful things, wouldn't work at all so they went where they belonged and I went back to proper commercial valves that actually do what they say they are going to!!

Pete, I've looked for commercial stuff and can't seem to find anything that corresponds, or anything like. Suggestions please. It would aLSO mean I have to change BOTH valves.

Bob,

Yes I think you are right LMS. Have used them on one of my locos for years but think I may have reseated them and use nitrile balls.

I've ordered one from Live Steam Models. From the picture on their website it looks the same as what I have.

They are even painted black!

The valve that I ordered yesterday from LSM, arrived with today's post. That is exceedingly good service. It is also identical to the other one, so one happy bunny here!
