1 QV SERIES utterfly Valves KEY HIGH VUUM PROUTS, IN.'s QV Series butterfly valves are designed and manufactured to offer reliable performance, be versatile and offer an economic benefit. These valves have a narrow compact straight through design with a minimal internal surface area to maximize available pumping speed. KEY HIGH QV Series butterfly valves possess a quick quarter turn 90 actuation from the fully open to the closed position. Valve bodies are fabricated from 04L SS or 6061T6 luminum (dependent on customer choice) for corrosion resistance and a low out gassing rates. KEY HIGH QV Series valves feature four different flange interface styles: bolted, MET-SEL, ISO-NW and ISO-MF. Our wide range of flange interface styles allows the user to pick the exact flanging system for their particular requirement and saves on expensive enclosure space by eliminating adapter flanges. enefits of these flanging systems is rapid, convenient system assembly/disassembly and excellent flexibility. QV Series butterfly valves are ideally suited for the isolation of pumps, chambers, roughing lines and exhaust lines. Valves are mountable in any position. However, the correct or preferred method is to install the QV valves with the narrow side of the taper towards the vacuum pump. In this arrangement the pump will "pull" the flapper into the narrower side of the taper while the valve is in closed position effecting a better seal. KEY HIGH offers the QV Series valves in three distinct actuating styles; manual, electropneumatic and motorized operation. ll QV valves have small physical "footprints" and are high conductance shut off valves due to the straight through design and offer a significant cost advantage over a gate valve, as well as a much smaller physical foot print. QV Series valves from KEY HIGH VUUM PROUTS, IN. have been approved for use in some of the world's largest semiconductor equipment builders and I manufactures. New in this catalog is the locking handle option for the manually operated valves. locking handle is of a direct benefit in the exhaust line, as once set in the correct position will help eliminate under/over shoot issues from the throttle valve. KEY HIGH QV Series valves include these standard features: ll small cross section Viton seals bakeable to 150 with valve in open position ual Viton shaft seal /4" I through 6" I bores Mountable in any position or flow direction Each valve is helium leak tested at x 10-9 torr prior to shipment.0 Please call Key High at or us at for the most up-to-date listing of products and for pricing information.
