Standard Module Valve

This valve can be inserted into a standard module causing the air to only travel in one direction.

This is included by default with the standard module. This item comes in black.

This is inserted into the centre of the standard module, with a hard push. Take note of the orientation you insert, as this will determine the air flow.

This item does not include the standard module or gas mask. This is a novelty item, use at your own risk.
