VALVE NOTES By the Man Behind the Powell
Valve
Ironing out Problems . . . for the synthetic fiber industry is nothing new to the W m . Powell Company. W e developed the first valves successfully used in the making of synthetic fibers. The biggest problem in synthetic production is IRON—the minutest trace can turn miles of filament brown at the flip of a coin, ruining it. That's why all Powell Synthetic Fiber Valves are made with specially controlled stainless steel— to assure complete freedom from iron contamina tion. Ferroxyl testing assures this. Next we subject them to a series of leakage and stability tests. And finally we install special seals for contamina tion protection during shipment. Result: Valving contamination no longer a problem for the syn thetic fiber industry.
This valve cleans itself In the refining of alumina, deposits build up on the Slurry Valves. It would be expensive and timeconsuming to be continually breaking down the valves for maintenance, so Powell builds "selfcleaning" devices into the valves. You turn a wheel that grinds the seating surface to remove minor deposits. A n d to cope with an extra heavy deposit, an impactor arm lets you sledge the seat open or closed. In addition, these valves are built to resist corrosion, erosion, vibration, thermal and mechan ical shock, wire drawing, fatigue, elastic and plastic deformation.
