hi can anyone suggest a good steam Globe Valve. I have bought several from different suppliers but seem to seal for a very short time. I need a 3 1/6 pipe fitting to supply my Injector had new one fitted only two weeks ago it's already seeping

Have you tried the PM Research globe valve? 1/4" x 40 thread available from Forrest Classics

or if you fancy machining your own from castings, have a look at PMR

They are easy to make up.

I have found the valves supplied by GLR Kennions to be very good quality. **LINK**

Sometimes, after a lot of use there can be a tiny leak at the valve stem but it is a simple matter to replace the graphite string packing. You may also like to experiment with O rings.

Alternatively, you may want to try the valves sold by Bengs Modellbau. **LINK**

They are made by Winfried Niggel and are rated to 6 bar.
