Description
The double eccentric butterfly valves are intended for chemical and general industrial applications.
Thanks to the double eccentricity principle, the seat wear is minimized, and this is why these valves have a long life.
The double eccentric butterfly valves ensure a valid bi-directional sealing and are available free of silicone or lubricating substances for applications such as oxygen services or paint systems.
The double eccentric butterfly valves are provided with two groups of cup springs that ensure high sealing along the valve pins even at high temperatures.
