2.Product description:
Penumatic rubber fender with chain protection
(1) High energy absorption
The amount of energy absorbed is the main technical performance indicators fender instruments. With the ship's tonnage growth, berthing operations, ship collision energy contact quay or other ships also doubled. Huge collision energy must rely on the contact area on the fender and enough to absorb sufficient deformation. Our ship fender use compressed air as the buffer medium to absorb ship impact energy and have good elasticity.
(2) Ultra low back pressure
The inside air of  pneumatic fenders is low pressure gas, the internal pressure increase is very limited during compression deformation. Due to the large contact area, unit pressure acting on the ship hull surface is very low, compared with other fender instruments, is not the common low back pressure.
(3) Inclined contact, good adaptability
Ship must have certain angle which have the possibility of contacting the side of the shore. As the inclined interface of sea inflatable fender, its adaptability is much higher than other fender.
Â
(4)Floating performance is good, not subject to tidal influence, fender can be maintained in the ideal level
Â
Pneumatic fenders floating on the water surface (more than 50% of the volume), along with the change of position is not relative to the tidal fluctuation. Especially the ship as the waves rolling, cylindrical inflatable fenders with rolling, the friction force is very small. So it will not damage the coating surface of the hull, and also decrease the moving.

The knife Gate Valve employs straight through structure of flange type or wafer type. It is metal-to-metal sealed or soft-sealed. When being opened or closed, the valve has small friction, so, a long service life, because the wedge and the sealing surface apply unique design, which has no concave cavity retaining water. The stem applies rising-stem type, which has left hand screw. When the stem nut is rotated, the opening scale of the valve can be directly viewed.
Driving mode: handwheel, worm gear, electric or pneumatic.
