Review on 🔍 Maximize Fluid Control with Control Devices Brass Check Valve by Harley Franchetti

Just what I needed for the fill hole on my 40 gallon auxiliary tank for my air compressor. I built an external auxiliary air tank out of an old gas water heater tank to use as an additional external tank for my 4hp air compressor. I installed a tank with a regulator, dryer, lubricator, safety valve, tank gauge and regulator gauge, drain valve to drain the water and fill the hole. I used a small manual valve that soon became a PITA and had to remember to open and close it when filling. My old original tank on the compressor was leaking so I wanted to be able to shut off the extra tank so it wouldn't leak back through the leaking original tank. So I decided on this check valve to replace the manual fill valve. Works very well and fast enough to fill a 40 gallon auxiliary tank. Topped up from zero to 110psi in about 5 minutes so that's enough for me. Seems to be holding up well so far. Seems well done.
