Operating the Argus Ball Valve
The Argus Ball Valve can be operated manually or automatically by an actuator.
There are three operation positions:
Open (the Argus Ball Valve opens by rotating to the left or counterclockwise)
Closed (the Argus Ball Valve closes by rotating to the right or clockwise)
Half-open (not intended for normal operation)
The Argus Ball Valve is open when the flat flanks of a shaft sealing head or the groove of a
square shaft sealing head are parallel to the flow direction.
For safety reasons the position of the Argus Ball Valve is recognizable by the ball
valve wrench.
