Prince Constant Volume Priority Flow Control Valves (RD400 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. 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. Max: 30 GPM, 3000 PSI.
