Ghibson - Model PD Series -Butterfly Valves for Abrasive and Corrosive Applications
Today for abrasive and aggressive application we have two types of valves. PD (PowDers) series is a rubber seated valve created for bulk handling, in which the disc geometry is studied to permit low torque open/close and reduce heavily wear of the seats over time.
This helps increasing lifetime of the valves and in the meantime permit use of smaller actuators, with considerable economical and space advantage.
