VV Venturi/Vacuum Generator Product Overview The PTFE Venturi/Vacuum Generator is designed for corrosive or high purity gas applications The design consists of two machined high purity PTFE body halves attached using a tongue and groove sealing mechanism The concept of a venturi valve is a short tube with a tapered constriction in the middle that causes an increase in the velocity of flow of a fluid and a corresponding decrease in fluid pressure This is used in measuring flow or for creating a suction The lack of moving parts eliminates the possibility of media contamination Features Integral nozzle on inlet body half PTFE wetted surfaces Benefits Eliminates the need for calibration and realignment Eliminates contamination and fluid compatibility issues Specifications Materials of Construction: Wetted Surfaces PTFE Non Wetted Surfaces PVDF 188 stainless steel Pressure Ranges: 0 to 120 PSIG (82 bar) Pressure ranges above are for operation at ambient temperatures For use at higher temperatures consult Pressure/ Temperature chart on page 3 OUTLET INLET 26 Temperature Ranges: 0° 150° F (17° 66° C) Ambient 0° 266° F (17° 130° C) Fluid Motive Fluid: Clean Dry Air N 2 or any other available gas Motive Consumption (Air): At 40 PSIG: 160 SCFM At 60 PSIG: 175 SCFM At 80 PSIG: 180 SCFM VACUUM Parker Hannifin Corporation Partek Operation Tucson AZ
