RBX Potable Water

The world leader in Air Valves Techonology


RBX Resized

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.

Advantages of Vent-O-Mat RBX “Anti-Shock” Air Release & Vacuum Break Valves Are:

Automatic Surge Protection
The unique Series RBX valve incorpates as standard, three design features to automatically protect a pipeline, under all pipeline operating conditions, from the destructive surge and water hammer phenomena. These features are independent of any mechanical devices ensuring reaction in a very low milli second time span.

Effective Air Release
The RBX design ensures effective de-aeration under all pipeline flow and operating conditions, via either one of three discharge orifices.

Vacuum Protection
The RBX series large orifice diameters equal the normal size of the valve. This ensures the least possible resistance to the intake of air and consequently the least possible negative pressure within a draining pipeline.

Guaranteed Performance
The RBX has been designed and developed to provide the optimum usable and safe performance relative to all functions. Selection data has been substantiated through third party testing and can therefore be confidently referenced.

VENT-O-MAT Series RBX “Anti-Shock” Air Release and Vacuum Break Valves are available in nominal sizes of DN25 (1″) to DN200 (8″) and for maximum operating pressures of PN16 (232psi), PN25 (363psi), PN40 (580psi) and PN64 (930psi). Valves are available in all stainless steel 304 or 316 on request.
