Great product, would purchase again.
This was very easy to install, I put WD 40 on the threads and let that soak for a couple days, the old one came out easily the new one threaded down easily with no leaks, functions very well, bled the air out of the line quickly.

The best air purging valve
It is an excellent product. It is used on my hot water boiler to remove the air. My tankles boiler is a water flow dependent and if there air it does not work. The big advantage of the valve besides removing the air is that can be removed to be cleaned without opening the plumbing thus you do not introduce air.

Vent valves
Parts were delivered promptly. So far working good, not leaking like ones I replaced. System has not been turned on yet, waiting for winter. Don't expect any issues.

Q: Looking for a auto vent to vent natural gas from well water. This would be placed above hot water tank(in hot water line) to vent outside. Would this vent work?
Asked by Tom 13 years ago

-
This valve will vent then gas out of the stem only. The efficiency would be increased by mounting the valve at the top of a bleed-off trap.

Yes it will, I used one on a hot water heating system to vent air.

Q: I understand this vents air under positive pressure, but if the system looses pressure, does it allow air to enter the system? IE.. if it is a float, how does it prevent the situation of lower system pressure than atmospheric? In the case of a system leak or negative pressure condition, can the vent allow air to enter?

Yes its a 2 way vent.... the only way to stop air from going back in, is to close it off. If the boiler is not piped properly the hyvent can also suck in air when the circulator kicks on.... kpc

- Another PexSupply Customer
in most hydronic set ups (even closed systems), there is a water inlet (a pressure valve) which will add more water to keep the pressure recommended for your boiler/system (mine is 12-15psi). therefore, a hydronic system will not have a lower than atmospheric pressure unless the water inlet does not function. If somehow you create a vacuum in your system then first your expansion tank (if any) will kick in and then this valve would probably let some air. In case of a water leak - if your water inlet does not work, the air will come in from the place the water is leaking... so it does not have to be the valve.

If the system loses pressure, the valve WILL allow air to enter the system to prevent negative pressure. The water enters the body of the vent and lifts the float when all of the air is gone. If the system loses pressure and water drains from the vent assembly, the float drops and allows air to enter.
