Mounting

The actuator is attached to the ball valve by means of a
hexagon nut (5). Therefore, the actuator can be easily remo-
ved from the ball valve. The O-rings can be maintained. This
guarantees high operating safety and reliability.
In order to disassemble the unit, proceed as follows:
Unscrew both screws (8).
Remove the actuator (1) from the valve body (7).
Remove the washer (2).
Remove the spring (3) and the indicator (4).
Unscrew the hexagonal nut (5).
Remove the housing support from the valve body (7).
Unscrew the gland screw connection (9).
Remove the spindle (10) from the valve.
Now the o-rings are accessible for maintenance or repla-
cement.
To reassemble the valve, carry out the steps in reverse
order.
Please carry out assembly in reverse order.
o-rings:
(12) 14 x 1.78 - EPDM
(13) 12 x 10 x 1 - PTFE
(14) 8.73 x 1.78 - EPDM
(15) 8.73 x 1.78 - Viton

When the valve is in the open position, the indicator is
on white or on red respectively. The structure of the ball
sealings allows the valve to close smoothly and with a very
low torque. This allows precise positioning and leak tightness
and guarantees high operating safety and reliability of the
ball valve.
