Butterfly Valves - LINESEAL III® (CLASS 150B)
SPECIFICATIONS: 250psig (1723kPa) maximum working pressure Meets or exceeds all applicable requirements of ANSI/AWWA C504 Standard Class 250B; NSF 61 certified Body - Ductile Iron ASTM A-536 (65-45-12) Buried service valves: I.D. and O.D. coated Above ground valves (ordered with either a hand wheel, position indicator on the actuator, or lever); minimum 8 mills epoxy coated interior and exterior. Seat-in-body design reduces seat failure due to corrosive buildup in the valve and pipeline (24"-48") Disc edge is 316 Stainless Steel Disc - Ductile Iron ASTM A-536 (65-45-12) (3", 4", 6" Stainless Steel ASTM A351 CF8M) Through-disc pinning provides a tight disc-to-shaft pin connection, greatly reducing the possibility of loosening through vibration Symmetrical disc for higher Cv and lower head loss (3"-20") Nonmetallic bearings prevent galvanic corrosion and provides lower coefficient of friction Chevron "V" type packing is self-adjusting to last the life of the valve
