Product Code:SAE ARP490
Title:Electrohydraulic Servovalves
Issuing Committee:A-6b1 Hydraulic Servo Actuation Committee
Scope:This SAE Aerospace Recommended Practice (ARP) is intended as a guide to aid in the specification and testing of electrohydraulic servovalves.The recommendations contained in this ARP are confined to the input and output characteristics of electrohydraulic servovalves, the primary focus of being four-way flow control servovalves. Three-way flow control servovalves are discussed to a limited extent, and terminology recommended for use with presure control servovalves is also presented. The information preented should be useful in standardizing the terminology, the specification of physical and performance parameters, and the test procedures used in conjunction with these components.The recommendations do not restrict nor attempt to define the internal design charateristics of servovalves. As such, the material is equally applicalbe to servovalves having different internal functioning, different ratings, different physical size, etc. In certain instances, standards for valve design are recommended to increase component interchangeability, as, for example, valve polarity, mounting bolt and fluid port locations.The specifications contained herin should be adequate to describe electrohydraulic servovalves. Additional specificaitons may be necessary to define special requirements for specific control systems. Also, specialized test procedures may be necesary to measure servovalve performance in these unusual specification areas. These considerations are beyond the scope of this ARP.【英文标准名称】:StandardTestMethodsforSewingThreads
