AVK rubber - a seal of quality
For over 40 years, AVK GUMMI has developed rubber components for the water, natural gas, healthcare and food industries. By maintaining complete production control through our high-tech facilities and one among the world's most advanced mixing plants, we are ready to offer unique rubber compounds of exceptional quality and uniformity
No matter which industry you are in, it’s essential that the rubber components inside your valves, hydrants and couplings are of the very best quality to ensure a safe, watertight seal and trouble-free operation, even after a few years without use. Through our rubber factory, AVK GUMMI A/S, we develop and produce our own rubber components to form absolutely sure they meet and exceed our customers’ – and our own – uncompromising standards of excellence. Our gate valve wedge design and other market-leading innovations provide the reliability you would like to safeguard your network, your supply and therefore the health and safety of your customers. This is often especially important for drinking water network operators, who can only make certain of an uncontaminated supply by choosing a valve supplier that gives such priority to quality and compliance.
Excellent ability to regain original shape
AVK’s rubber compounds have a superb compression set, which suggests the ability to recover the original shape after having been compressed. Even after a few years of operation, tiny pebbles, sand and other impurities won’t affect the rubber surface or the tightness of the rubber.
Test method for permanent deformation: The rubber is deformed by 25% of its original thickness at a constant temperature for a specific time. The pressure on the rubber is relieved and the layer thickness is measured after half an hour. The smaller the deformation, the better the memory effect.
Compression set (S) = (d0-d1)/(d0-d2)
d0 = original thickness of the test specimen
d1= thickness of test specimen after test
d2 = thickness of test specimen in compressed condition
State-of-the-art rubber technology
We enjoy from high-tech production facilities and from one of the world's most advanced, fully automatic mixing plants, where the raw materials are weighed and dosed automatically reducing risk of human error considerably. Our quality management systems include one hundred pc control of each rubber compound, full traceability, SPC control, FMEA and a zero-defect production. Additionally, our extraordinarily clean and safe production environment makes it possible to supply rubber components of a continuously high quality at the agreed time of delivery.
