You are going to have to tell us what it is you want to do or what it is
for and then we can tell you how to do it ... maybe.

I thought it was pretty clear. He wants a valve expert, particularly a
shallow-water valve expert. Ever heard of a shallow-water valve? I
haven't. I don't know if the guy wants anything to do with scuba - it
doesn't appear he's talking scuba.

I heard of shallow-water bi-valves.
Mmmmmm.

sorry...what I meant was ... I have had some problems with the exhaust
valve on vikings dry suits (both apeks & sitech). The let in water most
of the time. I am working in contaminated waters in a harbour in
Greece, and everything works fine, except the exhaust valves take in
water. I guess it is because of the shallow depth?

SO... what I wanted to know was if anybody knows a way to solve this?
Is it a malfunction in the valve? Or is it because of the lack of
presure? Is it because I move too much and trigger it myself?

Are there any valves (exhaust valves) made specifically for shallow
water diving?

THAT'S BETTER!!

It is a malfunction in your valve. Since it happens in both of yours, I
suspect that you aren't cleaning them. Basically, an exhaust valve is
is a simple diaphragm like a regulator, snorkel or purge mask exhaust
valve. It works by having air on one side build up to a point where it
is higher pressure than the water on the other side. When that happens
.... burp! Of course, on some valves there are springs and plate
"helpers" that adjust the amount of air required to open it, but that is
unimportant for this conversation.

If you are getting wet every dive from your valve leaking through the
diaphragm, then something is holding it open. That can be silt, dirt,
salt buildup, undergarment fuzz or just about ANY kind of other trash
you can imagine.

Since your valve is easily removed from the suit, try running warm (not
hot) water through from the inside out. Hopefully that will flush any
junk from the sealing area.

And, yes, there is a special valve for diving in polluted waters, but it
consists of twin diaphragms and will give you the same grief if you
don't take care of it.

Just my $.02
