It's that time of year again, I do work for a local music festival and build large art installations involving some wackiness.
As part of one this year, I hope to have a wood fired boiler producing steam in a large tank. As it reaches a certain pressure, I want it to vent the steam which will then exit through trumpets, airhorns, whistling kettles and assorted 'stuff'.
Any suggestions on a valve which will do this?
I imagine it venting into some sort of manifold with 6-10 pipes off this feeding the various devices. An adjustable valve would be a bonus so I can play around with pressures.
Before the H&S mob jump in, yes I'd intend fitting a secondary safety valve too.
