6.2.2. Storage
Storage of the valves should be carried out in an enclosed area, under the following conditions:
Temperature
from 15ºC to 30ºC
Relative humidity <60%
Open-air storage of the equipment is
NOT allowed.
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. CIP (Clean-in-place) cleaning
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
or
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 solution
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 (sterilisation-in-place)
The steam-sterilisation process is applied to all equipment.
DO NOT operate the equipment during the steam-sterilisation process.
The parts/elements will not suffer damage provided the instructions set out in this manual are
followed.
Cold liquid cannot be introduced until the equipment temperature is below 60°C (140°F).
Maximum conditions during the steam or superheated-water SIP process
a) Max. temperature: 140°C / 284°F
b) Max. time: 30 mins
c) Cooling: Sterilised air or inert gas
d) Materials: EPDM / PTFE / VMQ
