NASA MANUFACTURING AND TEST REQUIREMENTS FOR NORMALLY CLOSED PYROVALVES FOR HAZARDOUS FLIGHT SYSTEMS APPLICATIONS
|Publication Date:||24 June 2015|
The purpose of this Specification is to establish andimplement the manufacturing and test requirements and applications guidelinesfor normally closed (NC) parent metal shear-section valves. The Specificationis a guide for design engineers to develop more detailed requirements forspecific pyrovalve applications. Adherence to these requirements will reliablyprevent NC parent metal valve leakage or other failure-induced release ofhazardous fluids (liquids or gases) from National Aeronautics and SpaceAdministration (NASA) payloads on Expendable Launch Vehicles (ELVs). ThisSpecification does not address NC parent metal valve sizing, pressure drop, andother requirements.
