A soccer ball like any other ball has a valve that controls the flow of air in and outside the ball. The valve is a device with a spherical closure unit.
When the valve is positioned such that the bore is aligned in the same direction as the pipeline, it is in open position, and the air can flow outside the ball through it.
When rotated 90 degrees, the bore becomes perpendicular to the flow path meaning the valve is closed and air cannot pass through.
Due to the possibility of constant wearing on the bores, ball valves are not ideal for throttling applications. The body of the valve is usually made of steel and can be made more durable with nickel plating.
Most of the soccer balls are two-way, which allows the flow to travel precisely from the inlet to the exit. However, the three-way and four-way ball valves allow for current to move in multiple directions including 90-degree angles.
When deflating a soccer ball, one has to be careful not to tamper with the inner bladder or to make the valve hole too big when using a needle.
A soccer ball is deflated for many reasons like you want to store the ball, or you just want to take out a small amount of air if the soccer ball is over-inflated.
How to Deflate a Soccer Ball with a Needle
An inflation needle is one of the commonly used tools to deflate a football ball: you just need to insert it inside the black valve on the football ball.
Some people prefer that the needle should be lubricated with some water, saliva or spray lubricant so that the needle slides smoothly.
The needle should not be connected to a pump because the air inside the ball will not come out.
Slowly push the needle into the ball, making sure that you do not press the valve inside the football ball or puncture the inner bladder — both events will make the ball unusable; puncturing the inner bladder will call for another cost because it must be repaired for the ball to be useable.
Air starts coming out of the ball when the needle is inside the ball. When you begin to hear the hissing sound of air coming out from the ball, maintain the needle in that position. Hold the ball tightly and squeeze it to push the air out of the ball and prevent the needle from snapping.
TIP: Hugging the ball in your arms, standing or kneeling on the ball speeds up the process.
In case you want a small amount of air to come out of the football ball, just squeezing it with your hands is recommended.
Once the desired amount of air is out, slowly pull the needle out of the ball and store it in a safe place. Once the needle is out, the ball stops deflating.
How to Deflate a Football Ball without a Needle
If you want to deflate your ball and you realize you don’t have a needle, don’t worry.
Just use basic science to deflate the ball.
All you need is to clean the outside of the ball and remove all the visible dirt and debris from the surface.
Move things around the refrigerator to create room for the football ball on the top shelf. Place a cloth or dishtowel at the very back of the top shelf of the fridge and put the football ball on the cloth inside the refrigerator.
Air expands when it is heated and condenses due to cold. So you can use this method to regulate the amount of air inside your ball.
If you want a small amount of air to come out, you need to check the ball inside the refrigerator after a couple of hours.
How to Deflate a Soccer Ball with a Pump
A football ball can be deflated with an inflating pump. The inflating pump has an adapter needle that is used to inflate the ball.
Without this needle, a soccer ball cannot be inflated. This needle can also be used to deflate the association football ball.
The needle is moistened to smoothen so as to avoid wear and tear of the valves. It is then inserted into the valve of the ball; the air escapes out of the ball. If the desired amount of air is attained, the pump needle is slowly pulled out of the ball.
How to Deflate a Soccer Ball without a Pump
Sometimes you are on the football pitch and there is no needle, a pump or a refrigerator to deflate the soccer ball… all you need to have is a paperclip.
Just straighten the paperclip to look like a needle and moisten it using saliva or water. Insert it slowly into the ball’s valve and push it at a right angle to the center of the ball avoiding puncturing the inner bladder.
The air will get out through the space created by the paperclip up to the desired amount and then slowly pull out the paperclip to prevent any damages to the valve or bladder.
