CAUTION
Excessively long idle periods
Damage to the valve!
▷
Check the function by opening and closing the valve at least once or twice a
year.
CAUTION
Use of levers
Damage to the valve as a result of excessive forces!
▷
Only actuate handwheel-operated valves by hand.
▷
Levers may only be used in exceptional cases and in compliance with the
following tables.
▷
Do not use levers in the area of the position indicator.
Permissible torque limits for levers
As the valve can be damaged by applying excessive force, it is not allowed to use
levers to move the handwheels of nominal valve sizes up to and including DN 125.
On all nominal sizes greater than DN 125, suitable levers may be used up to the
following torque limits:

Torque wrenches with hexagon socket shall preferably be used, which are placed
over the hexagon stem nut (925) after the handwheel has been removed.
7.1.3 Travel stop
The globe valves are always supplied set for maximum valve travel. The setting can
be adjusted as required using an Allen key. To do so, remove the plug from the
position indicator and adjust the screw plug. The requisite Allen key sizes are listed in
the table below.

7.2 Shutdown
7.2.1 Measures to be taken for shutdown
During prolonged shutdown periods, ensure that the following conditions are met:
1. Drain fluids which change their physical condition due to changes in
concentration, polymerisation, crystallisation, solidification, etc. from the piping.
2. If required, flush the piping with the valves fully opened.
