Compensated 2-way flow regulator. Two chokes in series are present in the valve. The first corresponds to the one that is adjustable using the knob; The second, controlled by the pressure prior to and following the first throttle, guarantees a constant pressure jump between the previous phase and the phase following the adjustable throttle. Under these conditions, the preset flow value remains constant within a tolerance field of ±2% of the full scale flow for the maximum pressure variation between the inlet and outlet chambers of the valve.
