Internal chamber (central) supply hole

CLOSED VALVE ADJUSTMENT
1) Pressurize the internal chamber (central) with the least pressure enough for the movement of the internal pistons (it can be noticed
from the outside due to the partial rotation of the shaft)
2) Unscrew the safety cap completely (1)
3) Rotate the screw (2) in a clockwise direction if you want to increase the closing angle, in a counter-clockwise direction if you want
to decrease such angle.
4) Reset the cap
5) Remove the pressure from the internal chamber
6) Verify that the adjustment obtained is the desired one, otherwise repeat the operations from step 1.
