WefTec - Live demonstration of Physical side-by-side Vacuum flow comparisons of the new Streamlined Vent-Tech® SWG valve shows over a 40% performance increase over the old design
First major public release of the Vent-Tech® range of Water & Wastewater Combination Air/Vacuum Release Valves [ARVs] using a streamlined version of the classic Flat-Float Cylindrical [FFC] design. Onsite demonstrations of side-by-side comparisons of this new streamlined FFC showed the Vent-Tech® SWG model achieves more than a 40% increase in vacuum relief performance over the old valve design. A 2ARI, mod. D-020 was also tested, demonstrating the vacuum flows through Vent-Tech’s 2 SWG was over 500% greater.
