Abstract:
An adjustable splitter valve and control system for a pulp washing apparatus that includes at least one of a displacement zone and an extraction zone for displacing fluid from a pulp mat and a plurality of discharge conduits for discharging fluid from the zone, the splitter valve and control system comprising:a moveable valve body for directing fluid from the zone to one or more of the discharge conduits, the valve body being connected to an actuator, the actuator being in communication with a controller, the controller being in communication with at least one sensor disposed in at least one discharge conduit, the at least one sensor measuring at least one physical property of the fluid that flows through the discharge conduit when the valve body directs fluid through said discharge conduit, the at least one sensor sending a signal indicating a measured value for the measured physical property for each discharge conduit, the controller comparing the measured value to a predetermined or calculated value range for the respective discharge conduit, in the event the measured value falls outside of a predetermined or calculated value range for one or more discharge conduits, the controller sending a signal to the actuator to move the valve body.
