3. Receiving and installing
3.1. CHECK THE SHIPMENT
The first thing to do on receiving the valve is to verify that it is matches the delivery note.
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 are present
•Complete valve.
•Its components (if supplied).
•Delivery.
•Instructions 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.

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 3.8.1)
3.5. FLOW DIRECTION.
The recommended flow direction for the product passing through each of the valve types is indicated below. Following these
indications will help to prevent as much as possible any pipe hammering and the consequences of this caused during single-seat
valve closing operations. The recommended direction is always contrary to the valve closing movement, that is to say, the plug
shaft always works against the fluid pressure when closing the valve.
For type N, M type valves, it advisable to connect the fluid inlet to the valve at the lower opening.
For type-K divert valves, due to their design, it is advisable to connect the fluid inlet to the intermediate opening.

3.6. ASSEMBLY.
Once the location of the valve is defined, the pipe can be connected by welding the bodies of the valve or by means of
accessories (connectors). In this case, do not forget the seals and to tighten the joints well.
In K, M, and N-type (two bodies) valves, it is advisable to use connection adapters to connect one of
the bodies in order to facilitate disassembly of the valve.
Before welding the bodies to the piping, disassemble the valve to prevent damage to the joints.
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.
3.7. INSPECTING AND CHECKING.
Check the following before use:
•Check that the clamps and the nuts are well
tightened.
•Open and close the valve (applying
compressed air to the actuator or moving
manually if a handle is available) several
times to ensure that it operates correctly and
check that the shaft seal fits smoothly with
the valve body.

3.8. 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.
3.8.1. Weld / weld single-seat valve. Fig. N/K/M
•Disassemble the valve as indicated in section 7.
Assembly and disassembly
•Weld the valve body to the pipes.
•When welding the valve body, it is very important to maintain the minimum distance (dimension A) enabling
disassembly of the valve for later checks and replacement of valve parts (e.g. seals, springs). It is important to note the
difference when the valve has a control head. (dimension B)
•In K-type valves, it is advisable to use connection adapters to connect one of the bodies in order to facilitate
disassembly of the valve.

ED. 2009/11 Start-up 11
4.Start-up
The start-up of the valve can be carried out provided the instructions indicated in Chapter 3 – Receiving and Installation are
followed.
This equipment is suitable for his use in food process.
4.1. SINGLE-SEAT VALVE APPLICATIONS.
Single-seat valves may be cut-off or change-over type. Cut-offs are used to open and close the passage of fluid, whereas
change-overs are used to redirect the flow trajectory.
4.2. START-UP.
Before start-up, the responsible persons should be duly informed of the operation of the valve and
the safety instructions to be followed. This instruction manual should be available to personnel at all
times.
The following should be taken into consideration before starting-up the valve/actuator;
•Check that the pipe and valve are completely free from any traces of welding or other foreign matter. Carry out the
cleaning of the system if required.
•Verify the smooth operation of the valve. If necessary, lubricate with special grease or soapy water.
•Check for possible leaks and check that all the pipes and connections are watertight and free from leaks.
•If the valve is supplied with actuator, ensure that the alignment of the valve shaft with the actuator shaft allows for a
smooth operation.
•Check that the compressed air pressure at the intake to the actuator is that indicated in the Technical Specifications
(
Chapter 8 ).
•Mind the quality of the compressed air according to the specifications described in chapter 8 Technical Specifications.
•Operate the valve.
4.3. OPERATION.
Do not modify the operating parameters for which the valve has been designed without written prior
authorisation from INOXPA.
Do not touch the moving parts of the coupling between the actuator and the valve when the
actuator is connected to the compressed air.
Danger of burns! Do not touch the valve or pipes when hot liquids are circulating or when cleaning
and/or sterilisation are being carried out.

14 Maintenance ED. 2009/11
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
or
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)
