This controller is a supporting control device for regulating valves. This product has a wide range of applications and is also suitable for other similar types of regulating valves. The control objective is to adjust the opening of the regulating valve by setting the mixing ratio parameters or clean water parameters, thereby regulating the clean water flow to maintain a certain proportional relationship with the mother liquor flow and controlling the injection concentration. Once the relevant parameters are set, the entire control process operates in a fully automatic mode. Manual control can also be performed on the touch screen as needed.

It has been widely applied in various injection and production stations across all oil extraction plants in Daqing. The operation is **stable**. This product can also be used in various control scenarios with fewer control loop requirements.
