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.
