DIY ATO, with Hudson Valve

[reef6414]

As part of my tank build, I am adding a gravity fed ATO system. Rather than the standard float valve, has anyone ever used a Hudson Style Valve? I have seen them in use for water troughs etc. Just curious if they have a strong enough seal for use on a marine aquarium.

Any input would be greatly appreciated!

Don't think it would work. Reading their literature it takes a minimum of 8 psi at 8 GPM to seat the valve and shut it off.
