These look nicely made!
A diagram/photo of the innards would be great.
Two questions:
You mention putting a 60 micron filter on the intake on your website - how does this go with adding offboard gas when a small amount of water will get into the valve? Can the valve cope with this water? Is there an orifice that will get blocked?
You quote a flowrate of 4lpm what pressure is this with?
Thanks,
Neil
60 micron filter on the O2 MIV only. If you plan to have an offboard on O2, I would put a filter on the off board feed as well and/or disassemble and clean the valve after each saltwater dive where you pugged the offboard in undrewater. No problem if you keep it plugged from topside.
There is no orifice, but a flow opening is rather small on the O2 model. You can always increase it with a small drill
4lpm was measured with 140psiIP nonballanced 1st stage.
As mentioned above if the flow is small for you, 10 seconds with a drill bit will increase it. We figured that having a limited flow on the O2 add is a a good thing.
