Typical applications and industries: igh strength, one piece double "D" stem ensures reliable performance. Optional square drive stems available. 3 TOP PLATE ISO 5211 top plate facilitates easy actuation. Additional configurations available. APPLICATIONS Steam Dry Chlorine Caustic Corrosive Seawater Vacuum Sour as Oxygen Toxic Ultra Pure Water INDUSTRIES Chemical Petrochemical VAC Water Filtration Power eneration Food and Beverage Sugar Processing Refining Pharmaceutical Mining 4 EXTENDED NECK 4 Extended neck allows access to the packing gland when valve is fully insulated. FLOW BORE 5 SEAT RETAINER Uninterrupted seat retainer provides a high integrity sealing surface with available face-to-face options between mating flanges. 5 6 External travel stop in the top plate allows for an uninterrupted bore optimising the flow path and reducing the potential for turbulence. SEALIN SURFACE 6 RESILIENT SEAT Fully encapsulated energised seat provides bi-directional zero leakage sealing 7 CONTOURED DISC Engineered to maximise flow and minimise torque for optimal Kv values. 8 BODY An uninterrupted seat retainer provides a high integrity sealing surface between mating flanges. FUITIVE EMISSIONS Enclosed base eliminates leak path minimising fugitive emissions. Standard Stem Seal is designed and type tested to meet European Fugitive Emissions Standard EN ISO and TA-Luft VDI 244. Optimised body profile to minimise valve weight. 9 ENCLOSED BASE Eliminates leak path minimising fugitive emissions. 9 Enclosed Base Stem Seal 2 BRAY CONTACT T BCUK.SALES@ BRAY MC/CANNALOK EN I PERFORMANCE BUTTERFLY VALVE 3
