Large diameter butterfly valves

Series 35/36 heavy-duty, large-diameter, resilient seated butterfly valves are full-flanged versions rated at 75 and 150 psi, respectively.


Series 35/36 heavy-duty, large-diameter, resilient seated butterfly valves are full-flanged versions rated at 75 and 150 psi, respectively. Line is available in sizes of 60, 66, and 72 in. and has many design features and benefits of smaller Bray valves, including high Cv ratings, minimum parts exposed to the line media, reliability, and long service life. Bodies are drilled to be compatible with ANSI 125/150 or other international flange standards. Series may be bolted to allow downstream flange removal or cross-bolted for maximum resistance to line stresses. High-strength disk casting is spherically machined, hand polished to provide 360° concentric seating, bidirectional bubble-tight shut off, minimum torque and long seat life.
