VAVG SeriesInternal Training;Current Status of VA/VG;Agenda;Where it all started...;What are the objectives of the product?;Agenda;Operating Parameters Maximum operating pressure: 3500, 6000, 10,000 psig / 241, 414, 690 bar Operating Temperature: -40°F/-40°C up to 250°F/121°C Flow Capacity: VA Series Valve: Cv = 0.75 VG Series Valve: Cv = 2.0 Low Actuation pressure range: 60 psig / 4.1 bar Media Contact Materials Body: Brass, 316 Stainless Steel machined bar stock Seats: CTFE, PEEK, Tefzel? ETFE, Vespel? Valve Stem: 17-4 Stainless Steel O-rings: Buna-N, Kalrez?, Viton?, Ethylene Propylene (E.P.), Urethane Back-up rings: Teflon?, CTFE Other Cleaning: CGA 4.1 and ASTM G93 Weight: VA Series Valve: 3 lbs / 1.4 kg VG Series Valve: 5 lbs / 2.3 kg;Product Features;Popular Modification Features; Exceptionally low cost of ownership Long service intervals Simple cartridge design – replace all wear parts with one cartridge Labor cost for maintenance is reduced Dramatically reduce system downtime with highly reliable poppet valve technology Ease of installation, reducing installation time cost In-line serviceability – the VA/VG can be left in the system for service. Service time can be as little as 1 minute by replacing the valve cartridge.;High reliability and exceptionally long cycle life (250,000+ cycles) due to balanced valve non- rotating poppet/valve stem and linear actuation VA wins “Breakthrough Product” of the 2002 competition made by the trade journal that targets the process control industry called Processing Magazine In an independent test achieved over 250,000 cycles: 128 times over the leading brand’s other types of valve designs Controlling very high pressures with low actuation energy Fast actuation times Actuation times with 80 psig / 5.5 bar actuation pressure VA Series Valve: 50 milliseconds VG Series Valve: 75 milliseconds Actuation time for a ball valve is 0.15 to 5 seconds;What are the benefits of the product?;Agenda; Anywhe
