Disk shutters (butterfly valves)
A butterfly valve (a disk shutter) consists of two die-cast valve body halves made from aluminium, polymer-coated steel, or cast-iron disk and an elastomer gasket. The V2FS model has two identical flanges. It is possible to install a hand lever, a pneumatic actuator, or a gear reducer on a butterfly valve. They are all interchangeable. Thanks to their special design and the special materials used in their construction in various combinations, these valves represent the most advantageous and efficient solution.
