3.Receiving and Installation
3.1. CHECK THE SHIPMENT
The first thing to do on receiving the valve is to verify that it is matches the delivery slip.
INOXPA will inspect all the equipment before packing, although it cannot guarantee that the merchandise will arrive intact to
the user. For this reason, the valve received and any other article should be checked and, if it is found not to be in good
condition and/or not all parts are included, the carrier should submit a report as soon as possible.
Each valve has a manufacturing number engraved. Indicate the manufacturing number in all documents and correspondence.
3.2. DELIVERY AND UNPACKING
INOXPA will not be responsible for the inappropriate unpacking of the valve and its components.
3.2.1. Delivery:
Check that all the parts indicated in the delivery slip exist
Complete valve.
Its components (if supplied).
Delivery slip.
Instruction manual.
3.2.2. Unpacking:
Remove all traces of packing materials from the valve or parts.
Inspect the valve or its constituent parts for possible damage caused during transport.
Avoid any possible damage to the valve and its components.
3.3. IDENTIFICATION

ED. 2010/11 3.Receiving and Installation 7
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.
3.7. WELDING
The welding work can only be carried out by persons qualified, trained and equipped with the
necessary means to carry out this work.
Disassemble the valve before starting the welding work.

The time interval between each preventive maintenance may vary according to the working conditions to which the valve is
submitted: Temperature, pressure, number of operations per day, type of cleaning solutions used, etc.
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.

12 6.Maintenance ED. 2010/11
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 (HNO3) at 70ºC (150ºF)
0.7 litres HNO3at 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.
The parts/materials suffer no damage if the indications specified in this manual are observed.
No cold liquid can enter the equipment till the temperature of the equipment is lower than 60°C
(140°F).
Maximum conditions during the SIP process with steam or overheated water
a) Max. temperature: 140°C / 284°F
b) Max. time: 30 min
c) Cooling: Sterile air or inert gas
d) Materials: EPDM / PTFE (recommended)
FPM / NBR / VMQ (not recommended)
