RGX For Sewage & Effluent

The world leader in Air Valves Techonology


RGX Resized


An operating concept proven unsurpassed for air/gas release, vacuum protection and surge alleviation

Conventional sewage air valves are presented with major functional problems when operating on sewage and effluent pipelines transporting solids and other vicious substances. In fact, solids fats and oils quickly act to jam up standard air valves and render them useless, consequently unhygienic leaks threaten health and the ecosystem.

VENT-O-MAT Series RGX sewage air valves are a unique operating concept that has proven unsurpassed for air/gas release, vacuum protection and surge alleviation.

The Series RGX valve is maintenance free and constructed in corrosion and erosion resistant materials for dependable and lasting pipeline protection.

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

Vacuum Protection
Large orifice diameters equal the nominal size of the valve to ensure the least possible resistance to the intake of air and consequently the least possible negative pressure within a draining pipeline.

Discharge Performance 
Effective pipeline de-aeration is ensured, regardless of pipeline flow conditions, via either 1 of three discharge orifices.

All selection data has been sustantiated by third party testing and can therefore be confidently referenced.

Surge Protection
VENT-O-MAT Series RGX is the only sewage air valve available that is supplied as standard with an integral surge alleviating device to automatically dampen surge pressures in pipelines.

VENT-O-MAT series RGX economically offers the highest quality constrution and materials available in a sewage air valve.

VENT-O-MAT Series RGX “Anti-Surge” Sewage Air Release and Vacuum Break Valves are available in nominal sizes of DN50 (2″) to DN300 (12″) and for maximum operating pressures of PN10 (150psi), PN16 (232psi) and PN25 (363psi).
