The Ultraflo 300 series is available in 390/399 wafer style and 392/393 lug style designs. The two-piece housing allows for a one-piece investment cast disc stem creating maximum flow area, minimal product entrapment and smooth flow characteristics.
The 399/392 versions have slightly reduced I.D. for O.D. tubing service.
In addition, the following special features have been incorporated into our food service line of butterfly valves.
