- Construction features of  Floating Yokohama fender/ Pneumatic rubber fender/ Pneumatic Fender/ Inflatable Marine Rubber FenderÂ
Yokohama pneumatic rubber fender shall consist of an out rubber, reinforcement synthetic-tyre-cord layer, and inner rubber, vulcanized firmly.Â
The out rubber are used to protect the cord layers and inner rubber from abrasion and other external forces. This rubber compound have sufficient tensile and tear resistance strength to withstand anticipated weather conditions and severe usage.Â
The reinforcement synthetic-tyre-cord layer strong enough to maintain the internal air pressure of the fender.Â
The inner rubber layer seals the pressurized air inside the fender
Fenders of diameter 2500mm and larger equipped with safety valve for releasing excess internal pressure when the fenders are over-compressed accidentally.Â
-Â Type of Floating Yokohama fender/ Pneumatic rubber fender/ Pneumatic Fender/ Inflatable Marine Rubber FenderÂ
- Pressure requirements of Floating Yokohama fender/ Pneumatic rubber fender/ Pneumatic Fender/ Inflatable Marine Rubber FenderÂ
Evergreen-Maritime manufactures yokohama pneumatic rubber fender with 50kPa (pneumatic 50) and 80kPa (pneumatic 80) initial pressure. The internal pressure, endurable pressure, safety-valve setting pressure and hydraulic test pressure are also in compliance with the requirements of ISO17357: 2002.

A ballcock (also balltap or float valve) is a mechanism or machine for filling water tanks, such as those found in flush toilets, while avoiding overflow and (in the event of low water pressure) backflow. The modern ballcock was invented by José Antonio de Alzate y RamÃrez, a Mexican priest and scientist, who described the device in 1790 in the Gaceta de Literatura Méxicana.[1] It consists of a valve connected to a hollow sealed float by means of a lever, mounted near the top of the tank. The float is often ball-shaped, hence the name ballcock. The valve is connected to the incoming water supply, and is opened and closed by the lever which has the float mounted on the end. When the water level rises, the float rises with it; once it rises to a pre-set level, the mechanism forces the lever to close the valve and shut off the water flow. This is an example of negative feedback and of proportional control.
