How the 2-way Military valve works
When the valve is in the inflate (up/outward) position, the air being pumped in pushes the
spring-loaded plunger open, allowing air to enter the air chamber, but not letting it escape.
When the valves is in the deflate (down/inward) position, the spring loaded plunger is wide
open allowing the air to come rushing out of the air chamber. If the valve is in the inflate
position, the valve's plunger stem will be flush with the rim of the valve. If the valve is in the
deflate position, the valve's plunger stem will be inside, or lower than the rim of the valve. To
change the valve from the inflate position to the deflate position, simply use your finger to press
the valve plunger stem down/inward, and give it a ¼ turn. This will lock the plunger open
and allow the air to rush out. Use the same procedure in reverse to unlock the valve plunger,
allowing it to spring up into the inflate position.
Special note: If you are using a 12v inflator, like those that come with most inflatable mattresses
or those that plug into car cigarette lighters, you may need to have the valve in the deflate
(down/inward) position because those types of pumps typically do not provide enough air
pressure to press the plunger open to allow air into the air chamber. Additionally, 12v inflators
do not provide enough pressure to fully inflate the kayak, so you will need a secondary pump to
finish the job.
