Double-Ball/Flanged

Air Release Valves

Product Description

ARV-D Flanged, double-ball air release valve (air vent) is specifically designed to automatically vent air accumulations in water transmission lines. Its double-ball design effectively removes both small and large air bubbles, thereby minimizing the risk of air blockages in the system. The flanged connections offer a reliable and leak-proof installation, while its robust construction ensures long-lasting and trouble-free use.
