Dribble control logic for bulk handling
Bulk handling applications often demand precise control of the media during the discharge phase of the process. Typically, this can be achieved by introducing a 4-20mA DC signal to position the valve, as required, or alternatively, using discrete output signals.
ORBINOX UK has extensive experience in bulk handling applications, including the control instrumentation to achieve the desired logic.
In this application, our ‘XC’ series hopper outlet knife gate valve technology was selected. The subject valve is automated with our double acting pneumatic cylinder, incorporating our discrete dribble control logic. The dribble position is infinitely adjustable, and includes open, dribble & closed position remote indication. Additionally, the inductive proximity switches & solenoid valve coils have integral LED’s for local status confirmation.
