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.
