Valve assembly for enabling the flow of propellant to the spacecraft thrusters.
Mounts manual test valve and port, and manual charging valve and port.
A pyrotechnic valve opens when fired, allowing propellant to flow from the inlet to the
outlet (the firing cartridge is not included).
Package C was for oxidizer, and an identical package D was for fuel.
Nearly identical types of valve packages used in the Reentry Control System (RCS) and the
Orbital Attitude and Maneuvering System (OAMS). (This -11 unit is believed to be for the RCS.)
