Ozone Control

Controlling a gaseous service via a butterfly valve with any degree of accuracy is 100% dependent on the positioning of that butterfly disc. On small valves sizes common in the ozone treatment process, the position accuracy is even further emphasized, and the slightest movement of a butterfly disc can result in significant flow changes. The positioning accuracy of REXA Linear and Rotary Actuators truly shines on this service, as the dead-band accuracy (as tight as 0.05%) can position butterfly valve discs in small enough increments to promote accurate flow control, improving the ozone treatment process efficiency.
