Butterfly disc
The number that matters
Nominal pressure
16bar
The pressure class of the valve body at 20 °C. Working limits depend on the medium and its temperature.
Construction
Parts and materials
Butterfly valves are designed for use as shut-off or regulating valves for flow control in heat supply systems, water supply systems, in technological processes of food, chemical, oil and gas, pulp and paper and other industries.
The valves are opened and closed by turning the disk by 90°. Opening is performed by turning the gear wheel counterclockwise, closing clockwise.
