The flexible all-plastic Polyform valve is fitted into every inflatable Polyform product.
The V-10 valve is a non-return type of valve, fitted with a protective valve screw. For inflation, the screw has to be removed. Air is blown into the valve, and the valve screw has to be set back in place in order to fully secure any loss of air from the valve.
The V-40 valve is designed for easy inflation and deflation of our largest products. This is not a non-return valve. To inflate the product, the valve is opened by turning the valve screw anti-clockwise 3-4 times (do not remove the screw). Inflate through the center hole of the screw itself, and tighten the screw.
To inflate you can use a hand pump, but preferably an air compressor with a blowgun or - if you have a Polyform inflation adapter - with a tire nozzle. The products are designed to be inflated to 0.15 to 0.20 bar of pressure at 20° celsius. For use under tropical conditions the pressure has to be reduced to 0.05 to 0.06 bar. When inflating products without a pressure gauge, fill the fender/buoy until the walls start to expand, and make sure that you are able to depress the wall at least 1⁄2 inch (approx. 1 cm) with light hand pressure. (For tropical conditions: Approx. 1 inch (1,5 cm). Do not over-inflate as this will weaken the product and voids the warranty! The use of pressure gauge is recommended.
For maximum safety we recommend that only the lower swivel (under water) is used for mooring of the boat. The size of the buoy depends on the weight and the total load it will be exposed to. The dimension of the mooring iron bar and swivel should be chosen in accordance with the size and weight of the boat, weather conditions, the currents and wave height in the area the mooring is intended to be placed. Please remember to check your mooring for wear and tear at least twice a year. Do not expose the buoy to a load of more than 60% of its total buoyancy. Please also consider additional weight/load caused by marine growth, currents, wind and waves.
Fenders are made to protect the boat, also in tough conditions. When deciding on the size and numbers of fenders, plan for the unexpected, toughest weather conditions. Consider extra fenders in addition to the “basic need”. Depending on the shape of the hull, weight of the boat etc., consider a possible mix of cylindrical and/or spherical fenders to achieve maximum protection. Please note that the fender guide only can provide guidance, the local conditions are of vital importance. If in doubt, ask for professional advise.
Vinyl cleaner, mineral spirits or simply soap and water may be used. Stronger chemicals like Lacquer Thinner or Acetone will irreversibly harm the products by breaking down the chemical composition.
Most Polyform products are highly siliconized and can be difficult to mark, but permanent marker pens with fade resistant and quick-drying ink based on alcohol, are widely used.
