Application Double-eccentric butterfly valves are industrial valves, which are designed to fully open or close the passage of the working medium flowing through a pipeline. They can also be used for flow-control purposes. However, a  100% tightness of the valve cannot be guaranteed in a long-term use for control purposes. Working medium waste and service water drinking water hot water steam non-aggressive liquids and gases (natural gas, CO-gas, petroleum products, etc.) Butterfly valve is possible to deliver with surface protection which is done by coverage with plastic material (rilsan, halar). This surface protection together with the use of stainless steel material is widening the usage of butterfly valves for chemically aggressive or abrasive media and sea water.
