Product Code:SAE AS1225
Title:Oxygen System Fill/Check Valve
Issuing Committee:A-10 Aircraft Oxygen Equipment Committee
Scope: This SAE Aerospace Standard (AS) defines minimum standards of design, construction, and performance for two types of permanently installed, high pressure 12,800 kPa (1850 psig) and 13,800 kPa (2000 psig) oxygen system cylinder fill valves used in commercial aircraft. Refer to Purchaser's Specification for requirements which are beyond the scope or level of detail provided in this document.One valve has an adjustable pressure sensitive closing valve to automatically control the final pressure for a correct amount of oxygen in the system. The second valve incorporates an automatic shutoff feature designed to limit system overpressurization in the event maihntenance personnel do not stop system filling at the correc pressure. The intent of the fill valves is to control the rate of fill to limit the rise in temperature caused by compression heating to acceptable values, prevent oxygen back flow and prevent the ingestion of foreign matter that could cause contamination of the system.Note that some fill valves have integral supply line pressure regulators; for more information on supply line regulators, see AS1248.
