Detail of the helmet's visor seal valve.

Absent from this helmet is the pneumatic visor seal. Closing the visor actuated this valve and caused automatic inflation of the visor seal. The visor seal remained inflated until the deflation button on the valve (the red circle near the back of the valve) was manually actuated by the astronaut.
