Re: [PSUBS-MAILIST] Ball Valves

Hi Frank.

Not sure why George specifies the worcester valves.  I suppose they were just the ones he was used to using when he was making his boats.  They are excellent valves, just expensive.

The alternatives that i can get at my local shop are rubbish (cant remember the brand) and not up to the job.  I do like the lance ones as well, i have a couple of stainless 3/4 inch ones of those.  They are slightly cheaper.

i assume for your main tank vents you have an inlet pipe, valve and then an outlet?

Regards
James

I don't know why that particular ball valve is special, but I'm using
regular stainless ball valves from the plumbing supply house. They are mostly 1
inch but will have a few smaller ones too.
They're all rated at 600 psi. Is there a reason the Worcester valves are
specified? I might go with bronze valves if I can find some made in USA or
Canada. ( just politics)
On the flood valve, I'm using the ballast tank thru-hulls to flood the sub
if I need to. It may take a little longer to flood but it saves me an extra
 thru-hull and with the HP air injection on that system I can blow the
water back  out by switching valves and redirecting the water.( hope THAT never
happens) Frank D.
