MODULATING CONTROL VALVE ABSTRACT OF THE DISCLOSURE A flapper-poppet (new) that differs from a flapper- nozzle (old) in that the flapper-nozzle is a second stage operator that employs an amplifier which operates on de-amplified pressure. Although both the flapper-poppet and the flapper- nozzle are controlled by a conventional torque motor, the flapper-poppet is a first stage operator which operates on high supply pressure.
