Re: [APD] AAS Check Valve

[Vaughn Hopkins <hoppy1 at surewest_net>]

Thank you Douglas!  Once again I forgot all about McMaster as a source 
of such parts.  Google never seems to remember them either.  Those 
valves are so cheap they are probably a better deal, even with 
shipping, than a reasonably reliable ball valve.  I plan to put the 
check valve on the inlet to the bubble counter, a DIY unit, so it 
should only see the regulator outlet pressure at most, and the head of 
water above the reactor or about 2 psi or less almost all of the time.  
This check valve location protects the bubble counter from high 
pressure if the check valve cracking pressure goes up.   That is 
probably the direction I will go now.  Thanks again.
