1. The standard valve (V20) found in most of our products:
Remove the valve screw prior to inflation and replace the valve screw immediately after inflating the product to correct diameter/circumference. The rigid plastic valve screw is designed to fully seal the valve and to secure loss of air.

2. The smallest type of valve (V30) found in products like the FG fenders and the NB20/U3:
This valve does not require removal of the valve screw. Simply inflate through the centre hole in the valve screw, using compressed air or a hand pump with a nozzle that will fit into the centre hole of the valve screw. If the valve screw feels lose, tighten it carefully, not damaging the threads.

3. The larges type of valve (V40 = regulating valve) found in our largest buoys and fenders:
This valve is designed for easy pressure regulation and is not equipped with any bottom flap.
The screw shall not be removed from the valve. Open the valve screw (a few turns anti-clockwise to open for the airflow), fill air through the centre hole and close the valve (a few turns clock-wise).
Important: Do not tighten the valve screw with too much force as this may lead to the valve housing being deformed and leaking of air may consequently occur.
