Aerospace - General Requirements for Hydraulic Relief Valves
ARP4763
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.
Rationale:
This document was developed to assist the system designer in specifying the requirements for a hydraulic relief valve that prevents the development of excessive pressure.
