Thanks Al
The T1 is exactly the style I'm after. Half a Tech Taylor - it'll probably last for ever.

pipingdesign@yahoogroups.comSubject: [PipingDesign] Vacuum Breaker for Slurry
PipelineHi thereCan anyone refer me to a supplier of vacuum breakers suitable
for slurryservice on a cross country pipeline?I've tried using both water
pipeline vacuum breakers and preloaded checkvalves on a standpipe, but both
eventually jam up from the slurry grit.Something like a hollow (floating)
urethane coated ball in a verticalchamber with top orifice should do the
trick.ThanksSteveTo: pipingdesign@

RE: [PipingDesign] Re:Position of valves(ball valves and globe valves)Hi
Michael"It makes no difference which way we do it" is a phrase whichchills my
blood, as there is almost always a different outcome to adifferent method
choice. For example, if upstream service isolation is notthe decider, then ease
of operation, location of drip tray, installing firstthe valve which arrives on
site first, operators preference, standardizationof layout, ease of assembly -
the list is endless althought the benefit maybe small. Theres nearly always a
reason if some thinking is done. I suspectyour engineer is too lazy-minded to
think through the question. Your grainof salt is probably insufficient; I
suggest a bucket. Round thehead.CheersSteveTo:

as-builting,when I had askedthe engineer why they were different and there was a

reallywouldn't matter which waythey were oriented seeingas the ball
valves'purposes are to shut off, andthe globe valves'purposes are to

thefuel-oilline on each take-off foreach burner they had varyingarrangements of
a ballvalve, solenoid valve anda globe valve. Each ofthose three were present
atall burners, just onefloor had ball,solenoid, glove... and the other threefour
floors had ball,glove,solenoid. Apparently, from what I was told itmakes no
