HOW TO UNINSTALL
Place the unfixing tool in the part of the valve which is closer to the pipe. Relief the pressure in the pipeline by opening the valve and allow the fluid to come out; unscrew the connections from the valve.
It is important to verify the valves periodically to make sure that the valve is in good working conditions. The valve is supplied at opening position.
The opening and the closing are made by a 90° rotation of the handle. In the opening position, the handle is along the body of the valve, while in the closing position the handle is across the body. The ball valve is an interception valve and not a regulation one, therefore it must be completely opened or closed; if left at an intermediate position, seals could be damaged.
Only if you have to empty the pipe system, to prevent from frost problems, the valve must be opened at an intermediate position (45°) up to the complete discharge of the liquid, after that the valve could be fully opened.
It is suggested not to use the valve for liquids with abrasive suspensions.

Personnel in charge must be trained and equipped with appropriate protection devices. Prior to disposal, disassemble the valve and separate the component according to various materials. Please refer to product literature for more information. Forward sorted material to recycling (e.g. metallic materials) or dispose it, according to local and currently valid legislation taking into consideration the environment.
