Composite Materials May Hold the Key to Success

Keystone Composeal’s double D shaft design gives a clear visual indication of disc position when the valve is installed in the pipe line and four multidrilled locating holes comply with PN 6/10/16 and ANSI 150 and guarantee perfect concentric positioning between pipe flanges. The one-piece disc-stem minimises hysteresis problems, makes Composeal suitable for regulating flows, and ensures the shaft remains dry, to eliminate crevice corrosion between the shaft and disc.
