Product Code:SAE ARP4493
Title:Aerospace - Direct Drive Servovalves
Issuing Committee:A-6b1 Hydraulic Servo Actuation Committee
Scope:The recommendations contained in this ARP are primarily confined to the input and output characteristics of Direct Drive Servovalves (DDV). The only exception to this approach involves the definition and specification of chip shear force, which is not typically measurable by nondestructive external testing. The information presented should be useful in standardizing the terminology, the specification of physical and performance parameters, and the test procedures used in conjunction with these components.
