Bray Controls has designed a blow-out proof stem for the series 40 butterfly valves. The stem will become the standard on all series 40 valves, replacing the old stem design. The whole series is in compliance with the latest edition of the API 609 code for high performance butterfly valves. Available in both wafer and lug style bodies, these valves offer proven bi-directional sealing to full ANSI Class 150, 300 or 600 ratings. Standard body materials are either carbon steel or stainless steel.
