RBX Potable Water

The world leader in Air Valves Technology

Vent-O-Mat Series RBX “Anti-Shock” Air Release and vacuum Break Valve

Has all the functions of a standard Double Acting air valve with the addition of an “Anti-Shock” Feature, Sometimes referred to as a Triple Acting Air Valve or Three stage Air valve.

The Unique defence against pipe bursts and pipeline system damage!

Vent-O-Mat Series RBX has evolved from a long lineage of research and development into a product that has proven unsurpassed for air release, vacuum protection, surge alleviation and pipeline flow enhancement.

The basis of the Vent-O-Mat design is in the understanding of the physical laws that govern air valve and pipeline operation. Reaction to pipeline dynamics is therefore instantaneous and protection provided is relevant to the pipeline’s needs.

Vent-O-Mat Series RBX truly represents the pinnacle of valve design evolution. This valve design provides the most comprehensive, effective and efficient pipeline protection relative to initial cost of any other available pipeline component.
