Reviews
I replaced my old check valve same part number that was on my aircraft for 10 years, new one works as advertised.
Installed in a gravity feed system, in parallel with a Facet boost pump. This valve is indeed free flow (zero PSI breakout pressure) and as such works well in the gravity feed system, when the pump is turned off. The pump is only turned on for extreme nose up attitudes.
The item works great at sealing as a check valve. I had to open up and clean the seats from dust and once clean it worked great. I used it for vent and gas applications.
Not as represented, will not operate in light flow conditions

It leaked, did not work

ONE WAY CHECK VALVE 10630
Tried two of these. Both leaked and I ended up with fuel all over the floor of my hanger.
Failed, wasted $75 worth of fuel on the floor. Was in the upright position.
Since it is not spring loaded, it never worked and it was in a vertical position.
