Description

    Apollo Program: Command/Service Module Supplemental Propulsion System Helium Relief Valve. An important valve manufactured by Calmec Manufacturing Corporation for North American Aviation under NASA contract number NAS9-150. It has an assembly date of April 1965, and measures 6.5" x 3.25" x 3". This valve is a component of the propellant pressurization system and provided venting of excess helium pressure (should such a situation occur) on the initial start of the system by pyrotechnic valves. The unit contains a rupture disc (diaphragm), a filter assembly (to capture any debris from the ruptured diaphragm), and the relief valve assembly to bleed excess helium pressure. Excellent condition.

    This was my first time dealing with an auction house, and I am 100% completely impressed with Heritage. There is not an aspect of this process that I have a critique for.
