Pneumatic burst valve - what's it's real name?

I assume that you are Newcastle- that is 'on Tyne'
Why not try Shiremoor Compressors in Front Street, Seghill?

It's a long time since I dabbled in compressors but they were very helpful then.

loply:
Hi guys,

Thanks for the replies.

Fergus, I had no idea it was there, will remember in future though.

In the end I made a burst valve from two parts on the lathe and a tin foil insert. I tested different sizes till I found one that consistently splits at about 80psi.

To replace it you just unscrew the top cap, cut out a new bit of tinfoil and screw em back together again!
