Hello,

I am relatively new to larger model steam locos. I have what to most of you will be a rather naive question. I have bought an inline water valve to fit to the injector water supply of a 5" loco; one of those valves with a 4" long control. The shaft fits into the valve but doesn't engage with anything. What are the usual methods of locating this? I have seen grub screws and pins used. Forgive my ignorance but can someone advise me.

Thanks

M

Hi Michael welcome to the forum there are loads of people to give advice here but it helps if you give a locality and an indication of machinery etc.

Thanks, David.

I am in Co.Durham. The loco I have is a 5" gauge 'Dougal'. It's a very basic slip eccentric loco but water feed relies only on either the bypass valve or hand pump. Therefore I am fitting a No 2 injector. There is plenty of room for pipework, etc. so I chose to use the inline water valve mounted under the cab floor. Now that I have the valve I can't see how the handle is fixed within the valve.

Hi Michael,

(4" long control. The shaft fits into the valve). Are you refering to an extension for the valve spindle ? (Photo ?)

If so, the normal practise on full size engines is to have a square sectiion on the end of the valve spindle and the extension rod has a head with a square hole that fits over the spindle.

Paul.

Yes, that's right, Paul. There is a hole in the top of the valve spindle, The extension rod fits snuggly into that but both are circular so there's no way it can engage and open/close the valve. There is about 3/16" of the valve spindle proud of the valve mounting boss. It's not a lot but it may be enough to drill a hole through for a locking pin or even a slot.

I am hoping the supplier will get back to me on Monday with their recommended method.

Thanks for the reply,

Michael

Reeves suggest soldering the handle once the position of the valve has been established.
