Beduan Brass 10500-VE Automatic Float Valve, 3/8" Male Thread Air Release Valve Air Bleeder Valve Vent Valve

Good quality. I like the adapter it comes with. Worked well.

The threads are metric. The description is 1/2" imperial. My system is imperial. I didn't attempt to use it for a couple of weeks after purchasing so hopefully it can be returned to Amazon.

Producto de buena calidad por el precio. Entrega rápida.

Using these to vent my pool heating system and they are doing a great job so far. Been in for a month and are working, system is fairly low pressure and these remove the trapped air well. They do allow the air back in when the pump is off as they don’t have check valve feature. I didn’t add a check here as I was afraid it would hurt the air removal with my low system static pressure (<10 PSI) when the pump is running. Being an open system the air accumulation is constant issue and my original design of manual valves didn’t work well. These allow the system vent and prevent air lock on startup…. My pool is 85 in May (helps a little that I’m in Phoenix)

As ordered
