[PSUBS-MAILIST] Ball Valves

["James Frankland" <james@guernseysubmarine.com>]

Hi All.

Everything plumbing related that they have in my local store is SCHED 40 including the valves.  They are only rated to 220 psi.

So, Im currently using specially ordered Worcester ball valves for variable flood, vent, cabin flood etc

They are the high pressure ones (cant remember the exact rating now) but the trouble is that they are REALLY expensive.

Any suggestions for some cheaper valves as i need to order a load of 1/2 inch ones and i nearly just passed away at the price of the worcester ones.

What sort of valves have other people used?

Thanks
James
