Av-Tek – Air Valves
Av-Tek Air Valves are engineered for efficient air management in water and wastewater systems. Available in lightweight polyamide fiberglass, stainless steel or durable ductile iron, these triple-function valves release air during pipe filling, admit air during draining, and vent air under pressure.
With NSF 61 certification, corrosion-resistant coatings, and low-maintenance designs, they ensure reliable performance and longevity in municipal and industrial applications.

PRODUCT DESCRIPTION:
An air valve has three main functions:
- It exhausts air out of the pipeline when the pipe is filling with water.
- It allows air back into the system when the pipe is draining or being dewatered.
- It allows air to escape when the pipeline is under pressure.
The Av-Tek series 5300 iron air valve works to keep air out of the pipeline. However, a standard ductile iron valve only performs the first and second functions (exhaust air out of the pipeline when filling with water and allowing air back into the system when draining). In order to have the third function, a series 5301 poly air valve is threaded into the valve.
