RF Valves RBX Air Release Valve

RBX Air Release Valves from RF Valve are Vent-O-Mat air release and vacuum break valves designed for water and other liquids with up to 5% solids. These valves support pipeline filling, draining, vacuum break protection, and controlled air discharge once the pipeline is fully charged.

The RBX series is positioned for applications where air management, surge relief, and pipeline protection are important to system performance.
