GEMÜ Butterfly Valves

Butterfly valves in plastic and metal

The butterfly valve comprises a ring-shaped body in which a ring-shaped elastomer seat/liner is inserted. A washer guided through a shaft swings through a 90° rotary movement into the gasket. Depending on the version and nominal size, this enables operating pressures of up to 25 bar and temperatures up to 210 °C to be shut off. Most often, these valves are used for mechanically pure liquids, but can also be used in the right material combinations without posing any problems for slightly abrasive media or gases and vapours.

GEMÜ butterfly valves are primarily used in industrial applications and the chemical industry, as well as the fields of water supply and water/waste water treatment. The concentric and single-eccentric designs are available as standard. However, the double-eccentric and triple-eccentric shut-off valves are also available for projects on request. Use of matched control components such as position indicators, positioners and process controllers allows GEMÜ butterfly valves to also be used in control circuits.
