BARBIERI RUBBER specialises in the design and manufacture of protective bellows and boots for hydraulic valve and hydraulic distributor levers. Forty-five years’ experience in the hydraulics sector has enabled us to perfect various rubber mixes that are resistant to hydraulic fluid, and at the same time resistant to atmospheric agents and direct sunlight.
Thanks to these mixes there is no problem fitting dust boots on hydraulic distributor levers in closed cabins, even when they are exposed to direct sunlight. The average life of the boot fitted on a hydraulic valve does not determine the average life of the valve itself, but after breakage of the boot any dust, dirt and water that may filter into the body of the valve will cause it to deteriorate rapidly.
Careful design and laboratory testing makes it possible to achieve standards of quality that were unimaginable just a few years ago: by selecting the most suitable polymer base, formulating the mixes using tried and tested recipes and designing the rubber protection carefully, it is possible to achieve a perfect seal on the lever, making it resistant to oil and grease and also to ensure an average working life that is more than adequate even in geographical areas with extremely hot or cold climates.
Another significant point is the aesthetic effect that a well-designed boot shaped to fit the lever can give to a hydraulic valve or distributor, particularly if the boot is capable of retaining its colour, surface finish and flexibility for a long period of time.
