Our Latest Z Valve

Z Valve 12SZG.jpg

The latest rendition of our Zero-Pressure-Sealing CARV incorporates several new features to extend duty times and minimize maintenance effort. This is useful for air/vacuum valves when they are installed in the most difficult application, involving high fat level wastewater that periodically experiences low pipeline pressures. New features also incorporate functionality testing and devices aimed at allowing ejection of accumulate debris without valve disassembly.

The Vent-Tech Z-Valve™ has firmly established a new standard in CARVs capabilities, and as market recognition spreads, the demand is getting larger in more ways than one. Photo shows the President of IVM, Rudy Lang III, standing by a 12” Z-Valve™ with a vacuum relief rating of over 18,000 scfm.
