Abstract
A servovalve for use with clear water is designed and constructed. The spool of the valve is supported by hydrostatic bearings, and the bearing fluid is used in its nozzle flapper system. The frequency response of the valve is measured and verified that it has a bandwidth greater than 30 Hz. A linearized analysis is made to explain the dynamic characteristics of the valve
