Plastic Automatic Exhaust & Air Intake Valve 3/4" 1" 1-1/5"
Plastic Automatic Exhaust & Air Intake Valve
Keep your micro-irrigation or pipe network running smoothly with this Plastic Automatic Exhaust & Air Intake Valve. Designed to be installed at high points and elevated sections of pipe networks, this valve automatically releases trapped air when water fills the system — preventing airlocks that can reduce flow efficiency and damage pipes. When the system drains, it opens again to allow air back in, protecting pipework from vacuum pressure. Available in three sizes — 3/4", 1", and 1-1/5" — and three color options to suit your setup.
How It Works
- Auto Air Release: As water enters the pipeline, air trapped at high points is displaced and pushed to the valve, which automatically vents it out of the system.
- Vacuum Break on Drain-Down: When water drains from the pipe, the valve opens to admit air, preventing negative pressure buildup.
- Threaded Connection: Easy threaded installation at high-point locations in irrigation, garden, or plumbing pipe networks.
- Durable Plastic Construction: Lightweight yet sturdy plastic body resists corrosion and is suitable for use in outdoor irrigation environments.

Frequently Asked Questions
Q: What does a plastic automatic exhaust and air intake valve do in an irrigation system?
A: A plastic automatic exhaust and air intake valve is installed at the highest points in a pipe or irrigation network. When water enters the pipes, it automatically vents trapped air out of the system to maintain consistent water flow. When the system drains, it allows air back in to prevent harmful vacuum pressure from building up inside the pipes.
Q: What sizes are available for this automatic exhaust valve?
A: This automatic exhaust and air intake valve is available in three sizes: 3/4", 1", and 1-1/5" (11/5"). All sizes feature a threaded connection for easy installation in standard pipe fittings, and come in 3 color options.
Q: Where should I install an automatic exhaust valve in my irrigation system?
A: For best results, install automatic exhaust valves at the highest points and local highlands of your pipe network. These are the locations where air naturally accumulates when water flows through the system. Proper placement ensures efficient air venting and protects the entire irrigation system from airlocks and vacuum pressure.
Q: Is this valve suitable for outdoor garden use?
A: Yes. The valve is made from durable, corrosion-resistant plastic, making it well-suited for outdoor garden drip irrigation and micro-irrigation systems. Its threaded design ensures a secure fit in standard irrigation pipework.
