ventively machined flange according the drawing (fig.1)
• n.6 nuts M16 UNI5588,
• n.6 grower washers Ø16 UNI1751,
• n.6 plane washers Ø16 UNI 6592.
Screw the nuts with recommended torque (25 Nm /
18.4 Ft·Lbs).
During the valve mounting pay attention to insert the
O-Ring gasket included in the delivery (fig.2/1).
Bleeding of the valve
If installed vertically pay attention that the bleed screw
(fig.2/3) will be placed in the highest point.
