Prince Constant Volume Adjustable Priority Flow Control Valves (RD500 Series)
Used in applications where two circuits are to be supplied by a single pump, such as power steering systems. In operation, the flow of oil supplied to the inlet is divided into two flows - the priority flow and the excess flow. The priority flow will remain constant with variations in pressure on either the priority or excess flow port and will also remain nearly constant with variations in the inlet flow. Priority flow is adjustable in the field using the adjusting screw and is locked into place to maintain the setting. Max: 30 GPM, 3000 PSI.
