Apollo Saturn S-IVB Pneumatic Propellant Control Valve

This magnificent work of art is a Saturn third stage (S-IVB) Pneumatic Propellant Control Valve. The craftsmanship is just unbelievable.

A uni-directional Pneumatic Control Valve used to regulate the flow of Liquid Hydrogen Propellant (LH2) onboard the Saturn V (S-IVB) third stage, manufactured by Subcontractor Snaptite Inc (AERVALCO Co) Dec 1967 on behalf of Douglas Aircraft Company (Prime S-IVB) for NASA contact NAS7-101. This component was part of the pneumatic control system, which provided gaseous Helium (Ghe) pressure to actuate all S-IVB stage pneumatically operated valves with the exception of those provided as components of the J-2 engine.

[Control Valves]

I believe construction of such projects requires knowledge of engineering and management principles and business procedures, economics, and human behavior.

[valve actuator]

Valves vary from the extremely basic to the extraordinarily complex, and they are one of the oldest mechanical designs. Thanks for sharing great information, Hope to hear more updates from you ...
