HYDRAULIC CONTROL PANEL
MAIN RELIEF VALVE - limits hydraulic system pressure, Normal maximum pressure
setting is 1550 psi. System pressure over 1550 psi is relieved through the valve to the
SYSTEM PRESSURE GAGE - monitors hydraulic system pressure.
FLOW CONTROL VALVE - regulates flow of hydraulic fluid. Valve can be adjusted
manually to achieve desired speed of the conveyor and stacker.
CONVEYOR DIRECTIONAL CONTROL VALVE - controls direction of fluid flow to the
conveyor motor. Positioning of an internal spool determines the direction of conveyor
motor rotation. The valve may be electrically powered by the conveyor switch or manually
operated by pressing the buttons at either side of the valve.
