Frequently Asked Questions

What is a VAL-MATIC combination air release/air vacuum valve used for?

A VAL-MATIC combination air release/air vacuum valve is used in clean water pipelines to automatically exhaust large volumes of air during system filling and admit air during draining, while also releasing accumulated air under pressure. This prevents vacuum collapse, reduces surge damage, and improves system efficiency in municipal water, irrigation, and industrial applications.

How to install a VAL-MATIC combination air valve?
