Dan,
The valves your referring to are the main control
valves to put air onto each of the ballast tanks. The valves called out
aren't available any longer as far as I know. It really doesn't matter at
all what type of valves you use to replace them. I just used quarter turn
ball valves. I followed the schematic in principal but didn't use the
exact components that were called out on it. The important thing is that
your valves are of sufficient pressure rating and that you have two valves
for each hull penetration as called out. One valve for control and a
second for emergency. I think you can see some of what I used in the
posted pics of "Persistence." Also I used stainless fittings and
valves.
If I can help more, just ask, Dan H.

Subject: [PSUBS-MAILIST] K-350 Plan No.
13 question
Hello, this question is directed
to those who are building or have builded a K-350 Kittredge sub. I am starting
to install the plumbing lines in my sub and I have a doubt. In plan No. 13 the
item No. 7 description reads ?DIAPHRAM VALVE ? HENRY 6253? I can?t find any
information about this valve on the internet, all I know is that there are
three valves of this kind and they are connected to lines that goes to the
outside of the the sub. So? is it a check valve? Do you know where I can get
them? Or do you know a replacement for it, but the most important question?.
is it an actuated valve or is it a check valve? Or neither one. If someone
knows please help me out here. Thanks.
