About This Air Release Valve
This is a no-nonsense combination air release unit, built to handle the daily grind of water and sewage pipelines.
It's designed to automatically vent trapped air, break dangerous vacuums, and keep your system running smoothly without constant maintenance headaches.
Made from QT450 ductile iron with a stainless steel strainer, this venting solution is tough enough to handle harsh conditions and built to last.
How This Venting Unit Works
1. When filling the pipeline: It quickly releases large volumes of air to prevent air locks and flow blockages.
2. When draining the pipeline: It automatically breaks the vacuum to protect the pipe from collapsing.
3. During normal operation: It continuously releases small amounts of trapped air to keep pressure stable and reduce noise and water hammer.

FAQ
Q: Do I need electricity to run this?
A: Nope, no wires or batteries required. It works purely on mechanical action, so you don't have to worry about power outages or complicated wiring.
Q: Can this go underground?
A: Yeah, it's built to handle buried installations. The QT450 cast iron body holds up well to damp conditions, just make sure the top stays accessible if you ever need to check or clean the strainer.
Q: Is the strainer easy to clean or replace?
A: Super easy. You can just take the top apart, pull the strainer out, rinse it off, or swap it out for a new one. No need to remove the whole valve from the pipe.
Q: Will this fit my existing pipe?
A: It uses standard flange connections, so it should work with most common PN10/16 piping systems. Just double-check your pipe size and flange specs before ordering, and we can confirm it'll match.
Q: How long can I expect this to last?
A: If the water isn't super corrosive and you keep the strainer clear, it should keep working reliably for 5+ years. It's not the cheapest knockoff stuff, so it's built to handle daily use without giving out early.
