6 3.Receiving and Installation 2022/07
The buyer or user will be responsible for the assembly, installation, starting and operation of the valve.
3.4. LOCATION
Place the valve in such a way as to facilitate inspections and checks. Leave sufficient space around the valve for appropriate inspection, separation and maintenance (See Section 3.7.3).
3.5. ASSEMBLY
Once the location of the valve is established, the pipe can be connected by welding the valve body and cover or by means of accessories (connectors). The check valve must be installed vertically and in the direction of the flow.
Excessive stress should be avoided during the assembly of the valves and special attention should be given to the following:
• Vibration which may be produced in the installation.
• Expansion of the pipes during circulation of hot liquids.
• The weight that the pipes can withstand.
• Excessive intensity of welding.
3.6. INSPECTING AND CHECKING
Check the following before use:
• Open and close the valve several times to ensure that it operates correctly and check that the shaft seal fits smoothly with the valve body.

2022/07 6.Maintenance 11
6.2.3. Spare parts
To request spare parts, it is necessary to indicate the type of valve, the position and the description of the part which can be found in the Technical Specifications chapter.
6.3. CLEANING
The use of aggressive cleaning products such as caustic soda and nitric acid may cause burns to the skin.
Use rubber gloves during the cleaning process.
Always use protective goggles.
6.3.1. Automatic CIP (cleaning-in-place)
If the valve is installed in a system provided with the CIP process, its disassembly will not be required.
Cleaning solutions for CIP processes.
Only use clear water (chlorine-free) to mix with the cleaning agents: a) Alkaline solution: 1% by weight of caustic soda (NaOH) at 70ºC (150ºF)
1 Kg NaOH + 100 l. of water = cleaning solution o
2.2 l. NaOH at 33% + 100 l. of water = cleaning solution b) Acid solution: 0.5% by weight of nitric acid (HNO
3
) at 70ºC (150ºF)
0.7 litres HNO
3
at 53% + 100 l. of water = cleaning
Check the concentration of cleaning solutions; it may cause the deterioration of the watertight seals of the valve.
To remove any remains of cleaning products, ALWAYS perform a final rinse with clean water on completion of the cleaning process.
Before beginning the disassembly and assembly work, clean the valve inside as well as outside.
6.3.2. Automatic SIP (sterilization-in-place)
The process of sterilization with steam is applied to all the equipment including the pigging.
Do NOT start the equipment during the process of sterilization with steam.
