Application: Valve which allows the flow rate in P to be kept constant at a set value, independently of the required pressure and the flow rate entering the valve. The excess flow is discharged into B and is available for a second use. Port B is also insensitive to pressure variations but not to flow rate variations.

Assembly: Connect port E to the power supply and P to the actuator or to the line of a hydraulic system in which flow regulation is required. Connect B to the tank or to a second actuator.
To adjust the inlet flow rate to branch P, screw and unscrew the handwheel after loosening the lock ring nut.

E connection – Maximum inlet flow rate 80 liters per minute
P port – Maximum regulated flow rate 60 liters per minute
