Installation & Maintenance Instructions
Ball valves for all applications with an anti blow-out

cavity.
1. General
For the safety and reliability of ball valve delivered by Raimondi, we recommend you to follow the
directions for use described in this manual.
Proper maintenance is a guarantee for a correct operation of the equipment.
2. Subject
This manual deals only with the maintenance of Raimondi valves.
The electrical, pneumatic or hydraulic actuators are described in their own maintenance manuals
supplied by their manufacturers.
3. Storage
Each valve is protected in our workshop by means of:
• Plastic plugs on both ends (temporary)
• Peel-off varnish on the clamps (temporary)
• An external painting
• The lubrication of the passage port (temporary)
The temporary protections have to be removed before installing the valve on the pipe.
