1. ELECTRICAL AND PNEUMATIC ENERGY SUPPLY
- Use expert personnel for installation/uninstallation operations;
- Check that the air pressure and quality are correct (see "Technical
Data");
- Check the power supply to the control unit is correct (consult the
relative instruction manual).

B = Downward movement of the valve member
In single acting valves there is only one of the aforementioned
commands.
2. REDUCING THE STRESS TO WHICH THE VALVE IS SUBJECTED:
- Vibrations;
- Thermal expansion of the piping;
- Excessive welding;
- Overload.
CAUTION!
The seal seats may become deformed or cause valve malfunctioning.
3. CORRECT DIRECTION OF FLOW:
Flow in the opposite direction to valve closure minimizes
water hammer.
