252 Servovalve Performance Characteristics
Introduction
252 Servovalve Performance Characteristics
The flow versus frequency performance curves are shown in the following
figures. They indicate the typical performance capabilities of the servovalves at
various frequencies. The curves are derived by driving the servovalve at the
indicated frequency with a sine wave control signal and ± full current to the coil.
Note Performance in the following graphs are with 21 MPa (3000 psi) pressure
supplied and 7 MPa (1000 psi) pressure drop across the servovalve.
