This document is a Qualification Requirements form for a Solenoid Valve (National Stock Number 4810-00-720-4725, Part Number 1374-589867) dated 19 February 2025. The document specifies stringent qualification criteria for manufacturers seeking to supply this component, with a focus on maintaining high quality and maximum operational safety.

The qualification requirements are divided into two primary sections: those established prior to and after 19 October 1984. For both periods, only actual manufacturers who have successfully completed all testing required by the original design company, or manufacturers that have completed testing on items determined by the government to be similar in complexity and criticality, can be considered approved sources. The document emphasizes strict prequalification of sources through the DLA Aviation Source Approval Request Guide, indicating a rigorous selection process for this critical solenoid valve component.
