Press Release


The design of the basic Flat-Float-Cylindrical ARV has remained stagnant for almost 20 years.  The SWG is a Combination Air/Vacuum Valve [ARV] designed for wastewater applications.  It uses streamlined internals to significantly increase the flow performance under vacuum relief conditions.  The SWG provides 30% more flow than some base designs.  Research indicates that additional flow control devices will be able to deliver improvements of almost 60% over some of the base designs.

In many cases this will allow pipeline designers to use a 3 Vent-Tech®valve in place of a 4 valve (including savings on smaller tee-off fixtures and isolation valves).
