If the valve is installed in a system with a CIP process its disassembly will not be required. EPDM is
the standard seal material that will be used for CIP cleaning, both in alkaline mediums and in acid
mediums. The materials of the seal NBR and FPM are not recommended.
Two types of solutions can be used for CIP processes:
a. alkaline solution: 1% by weight of caustic soda (NaOH) a 70ºC (150ºF). To make this solution:
1 kg NaOH + 100 l H2O1= cleaning solution
2,2 l NaOH al 33% + 100 l H2O = cleaning solution
b. acid solution: 0,5% by weight of nitric acid (HNO3) a 70ºC (150ºF). To make this solution:
0,7 l HNO3al 53% + 100 l H2O = cleaning solution
1) only use chlorine-free water to mix with the cleaning agents
When ordering spare parts for valves and/or actuators which operating in potentially
explosive atmospheres you should indicate that to be for valves and/or actuators which
operate in ATEX areas and the features of this area. If there is no indicate this informa-
tion INOXPA is not responsible that the valves and/or actuator operated with parts no
suitables for the classied area where is installation.
Before start the assembly and disassembly works of the valve and/or actuator take ac-
count of the presence or possible formation of potentially explosive atmospheres.
