humans.
Valves DN200 (8”) and larger are equipped with attachment points (tapped holes). Add eyebolts to
these attachment points for lifting. The attachment points are indicated on the dimensional drawing of
the specific valve part number (available on request).
Never lay the valve down with control and actuating unit downwards as it may be damaged.
