Product Code:SAE ARP4945
Title:Aerospace-Solenoid Valve, Hydraulic, Three Way, Two Position, Direct Acting
Issuing Committee:A-6c5 Components Committee
Scope:This SAE Aerospace Recommended Practice (ARP) is intended as a guide to aid in the specifying and testing of direct acting three way, two position, single and multiple coil, normally open and normally closed solenoid valves used for the pilot actuation of hydraulic control systems and the control of hydraulic components.The information presented should be useful in standardizing terminology, in specifying requirements and performance parameters, and in defining test methods.The recommendations do not restrict or attempt to define the internal design features of solenoid valves. Standard mechanical, electrical and fluid porting interfaces are recommended to provide commonalty, interchangeability, design flexibility and to be more affordable.In general, this recommended practice is directed toward solenoid valves for use in military and commercial flight control and hydraulic actuation systems.For military aircraft applications, this recommended practice covers solenoid valves for use in hydraulic actuation systems of the following types as defined in AS5440 with rated operating pressures to 8000 psi (55,160 kPa) and flow rates typically less than 1 gpm (3.785 L/min).Type I-65 to +160 掳F fluid temperature(-54 to +71 掳C)Type II-65 to +275 掳F fluid temperature(-54 to + 135 掳C)For commercial aircraft applications, the information and guidelines of ARP4752 are considered. References are made to several documents that address phosphate ester hydraulic fluids. Detail Specification requirements, however, may need to be modified for a specific application.When recommended by a paragraph, the word "should" is used. The word "shall" is used to designate a firm requirement of a paragraph.
