This SAE Aerospace Recommended Practice (ARP) establishes the requirements for the design, manufacture, and qualification of four hydraulic switching valves used in airborne applications. Two are pressure operated, Type IA and IB and two are solenoid/pilot operated, Type IIA and IIB. They are applicable to four pressure classes 3000, 4000, 5000 and 8000 psi. The equipment as designed is intended to be installed in hydraulic systems designed to AS5440 for military applications or ARP4752 and ARP4925 depending on the type of aircraft for commercial applications. Additional or refined requirements shall be contained in the detail (procurement) specification and these shall take precedence over any potentially conflicting requirements of this ARP or documents referenced by this ARP.

This SAE Aerospace Recommended Practice (ARP) establishes the general requirements for hydraulic thermal expansion relief valves used in aircraft and missile hydraulic systems having operating pressures and temperatures as identified in 1.2.

Scope unavailable.

This SAE Aerospace Recommended Practice (ARP) is intended as a guide to define the requirements for aerospace hydraulic relief valves, including details pertinent to the design, performance, fabrication, and testing of the relief valves. NOTE 1: This ARP is for hydraulic system full-flow relief valves; ARP4835 has been developed to specifically cover thermal relief valves. NOTE 2: This document does not cover the modification of cracking pressure by external input; either hydraulic, electric, or pneumatic.

This SAE Aerospace Recommended Practice (ARP) establishes the general requirements for spring-loaded, normally closed check valves for use in Type I, Type II, or Type III aircraft and missile hydraulic systems having nominal operating pressure shown in Table 1.
