ABOUT ROTARY CONTROL VALVES

The Rotrol range of high-capacity butterfly valves has been developed to overcome the problems associated with control, cavitation and noise in conventional designs.

This innovative control valve performs especially well in severe service applications, where pressure drops tend to be high in the controlling position but where high-capacity throughputs at low pressure drops are also required
