Industrial Valves
Position Indicator and key direction
(Fig. 6)
On versions with a coupling, the disc position is marked
by two red dots. In the closed position, the imaginary
connection axis between the red marks is perpendicular
to the flow direction
Note the key position on versions without coupling.
The valve closes when the drive shaft is rotated clock-
wise (right-turning closure).
