Valves, Actuators & Pump Control


Continuous dosing control

October 2012 Valves, Actuators & Pump Control

PSV Mitech’s dosing control valves were used to dose reagents accurately into the flotation process in a ring main dosing system at a local mine. Specifically designed for the application, the system provided a continuous monitoring of the dosing state with feedback given every 15 minutes.

The medium was continuously circulated in order to reduce clogging, spillage and crystallisation. Various globe control valves were used in the ring main and a separate unit was used to control the pressure. The compact ring main dosing system replaced conventional dosing pumps and proved to be extremely cost effective. The valves also monitored the process, reduced reagent costs and eliminated human error.
