INSTALLATION AND MAINTENANCE INSTRUCTIONS

INSTALLATION

For correct operation of the valve, this must

be installed in horizontal position only as

indicated in Fig. 2. Different positions from

those indicated may cause non-correct valve

operation and/or quick deterioration of the

valve.

The following operations must be performed

only immediately before the installation:

1. Remove the protection caps of the end

faces.

2. Remove pin protection.

3. Check the pipeline sections upstream and

downstream. Make sure that there are no

solid particles or any other kind of dirt or

debris inside. If necessary, clean carefully

by using an airline.

4. Verify the flow direction in the line.

WARNING

Protect eyes with appropriate welding masks or

goggles during all welding operations.

WARNING

Verify that the direction of the line corresponds

to the flow direction indicated by the arrow on the

valve body.

Make sure that the materials of construction

listed on the valve nameplates (service and

temperature), are appropriate for the service and

fluid of the plant.

Flanged valves

Place the valve between the two pipe flanges,

and the gasket between the valve’s flange

and the pipe’s flange. Make sure that it is

positioned in the center. Assemble the valve to

the pipe by tightening the bolts according to the

torques given by the Engineering Company that

designed the plant.

Butt-welding valves

Position the valve and verify its alignment

with the pipe. Proceed with the welding in

accordance with the procedure indicated by the

Engineering Company that designed the plant.

Usually, the first weld layer will be made with

TIG, while following weld layers will be made

with the appropriate electrode for the valve

body material.

General notes

• Should one end not be connected to the line

for longer than half a day, the open end must

be properly closed and sealed in order to

prevent entry of dirt or debris.

• After the installation of the valve and before

the line testing, it is strongly recommend

cleaning the line in order to remove dirt

and/or foreign bodies that may damage the

tightness between the seat and the disc, and

the correct operation of the valve.

• We strongly recommend checking the torque

of the body-bonnet bolts, especially if the

valve is to operate at high temperatures.

Tightening must be done alternatively on

the bolts that are diametrically opposed, see

Fig. 3. The torque values are those reported

in Table 3.

INSTALLATION AND MAINTENANCE INSTRUCTIONS

START UP REQUIREMENTS

Before the start up of the plant, we recommend

to:

• Check that the lines have been accurately

cleaned.

• If the valve has been stocked for a long time

and should operate at high temperatures,

verify the tightness of the body/bonnet bolts.

Tightening must be done alternatively on

the bolts that are diametrically opposed.

See Fig. 3. The torque values are those

reported in Table 3.

• Check the tightness of the gland bolts.

• Check that the pin’s protection has been

removed.

• Check electrical, pneumatic and hydraulic

connection - if any.

• Check that the drain in the valve body is

properly connected to the plant draining

system.

• Check that the actuator is properly installed

according to section 8.

• Check that the torque/travel switches

are properly set according to actuator

maintenance manual.

SCHEDULED MAINTENANCE

Routine inspections

• Monthly check that there is no leakage from

the body/bonnet area.

• In case of leakage from the body/bonnet area,

tighten the appropriate the bolts according to

the sequence in Fig. 3.

• In addition to the above, please refer to the

actuator manual.

Preventive

• Check the space between the gland and

the bonnets every 12 months. In case of a

reduction of the space, restore the space by

installing a new ring packing.

• Remove the bonnet of the valve every 4 years.

Check the inside and verify that the valve

is not damaged, especially the disc pin and

the bushes. Re-lap the seats if necessary

and replace the body/bonnet gasket and the

packing.

• After 4 years operation, replace bushes 108

and 126.

• Disassemble the valve every 8 years.

Recondition the seats, replace the bushes,

the anti-clutch spacer, the gasket, the

packing and the keys. It is recommended

having a pin available during the operation.

• For the actuator, proceed as indicated in its

maintenance manual.

WARNING

An incorrect connection of the actuator is

dangerous and may cause irreversible damages

to the valve.

WARNING

The actuator should be energized before the

start up of the plant, in order to avoid damages

to the valve, and to minimize drops of charge,

maximizing the performance of the plant.

• During the start-up of the plant, verify the

packing seal. In case of leakage, tighten the

bolts alternatively.

• During the start-up, for the valves equipped

with lever and external counterweight, make

sure the counterweights are in the right

position for the intended service.

Under regular service conditions, operate

the lever in the sense of close position. When

discharged the lever should return by itself

to its former position. Without fluid in the

valve, the disc shall position itself in the close

position.

INSTALLATION AND MAINTENANCE INSTRUCTIONS

TROUBLESHOOTING GUIDE

Problems reported are not exhaustive,

they represent the most frequent ones.

Leakage from the packing

In case of leakages from the packing that

cannot be stopped by tightening the gland bolts,

proceed as follows.

• Packing may have hardened. In this case,

it must be replaced.

• The distance between the gland and the

bonnet is reduced. Thus, the packing cannot

be compressed. Packing must be replaced.

• Scratches or other marks are found on the

pin or the pin itself is bent. In these cases,

the pin must be replaced.

• The gland may be jammed on the pin because

of a non-uniform tightness of the gland

bolts. Loosen the gland bolts. Move the

gland and set it again; then tighten the bolts

progressively and uniformly.

DISASSEMBLING INSTRUCTIONS

Here below are the procedures to follow

to disassemble valves. Before starting any

operation, it is important to:

• identify the problem

• clean the area around the valve that is to be

disassembled

• prepare a box and/or a pallet where to collect

all pieces

• prepare a polyethylene sheet to protect all

components and to prevent particles from

entering the body of the valve.

For all the above cases it is absolutely

necessary to disassemble the valve as soon

as possible and perform an inspection of

the internal parts in order to reduce further

damage.

Leakage from the body/bonnet joint

• A leakage from the body/bonnet joint may be

the consequence of a long storage time of the

valve. The gasket may have lost elasticity and/

or the bolts may have loosened.

In the first case, the leakage will

progressively decrease, the gasket regaining

part of its elasticity with the contact of the

process fluid. A verification of the bolts

tightness will contribute to stop the leakage.

In the second case, bolts should be tightened

according to Fig. 3.

Usually these two actions are combined.

• Leakage under operation of the plant

requires the tightening of the bolts and

the replacement of the gasket as soon as

possible.

Leakage between seat and disc

In case of leakage between seat and disc,

check that:

• No foreign material is locked between seat

and disc, scratching the sealing surfaces.

• No foreign material is laid down between

the seats, preventing the disc from closing.

• During a previous closure the fluid has

laminated the seal surfaces, eroding these.

Jamming of valve along the stroke

If a higher torque is required at some points

when opening/closing the valve, proceed as

follows:

• Disassemble the valve, as body guides and

disc may start to seize.

Problems regarding motor operation

• Please, refer to the actuator instruction

manual.

During disassembling operations, identify all

pieces to keep track of the position/orientation

of the parts regarding the valve body.

WARNING

Before starting disassembling any part of the

valve it is very important to verify - for your safety

- that:

• the line is not pressurized

• the valve is not in temperature

• all electrical, pneumatic and/or hydraulic

devices have been switched off and

disconnected.

Actuator disassembling

1. Hold the actuator using the eyebolts with a

strip suitable to its weight.

2. Remove the bolts (79) that join the actuator

and the valve’s flange together

3. Remove the actuator from the pin of the

valve. If necessary use a lever between the

valve and the flange of the actuator.

Counterweight disassembling

1. Hook the counterweight’s opening

protection structure (276) with a steel

thread.

2. Remove the bolts that close the protection

of the counterweight and the opening itself.

3. Hold the counterweight’s lever (107) with a

strip. Then remove the blocking nut (115)

and the washer (211).

4. Hold the strip tight and remove the

counterweight. If necessary use a lever.

INSTALLATION AND MAINTENANCE INSTRUCTIONS

ASSEMBLING INSTRUCTIONS

Before starting reassembling is recommended

to verify the following points:

• Remove any dirt or particles with a wire brush

or abrasive cloth; remove any oil or grease

with a suitable solvent, to avoid damage

caused by foreign particles - in particular on

the sealing area.

• Never re-use the old gaskets, even though

they seem to be in good condition.

• During reassembling operations, match the

punched pieces so that they are correctly

assembled.

Packing assembling

1. Remove gland nuts (16) and bolts (15).

2. Lift the gland flange (10) and the gland (9).

3. Remove the used packing by means of a

steel hook-shaped thread.

4. For a better sealing, carefully clean the

packing room and the shaft. Make sure that

they are not damaged (scratches) and there

are not seizing signs.

The packing assembly must be done by

placing, in the packing room, one ring at a

time. Be careful to allocate them correctly and

press them to the bottom of the packing room.

6. Once the packing room is full, replace the

gland (9) and the gland flange (10) to their

original positions.

Body/bonnet gasket replacement

1. Before replacing the body/bonnet gasket,

clean the body/bonnet flange’s surfaces

carefully.

2. Fit the gasket in the seat, then align in

a parallel position the bonnet flange with

the flange in which the gasket is placed.

Do not use the bolts to align.

3. While tightening, make sure that the

flange’s pairing is completely parallel.

4. Tighten the bolts according to fig.3. In the

first tightening be careful to apply 1/4 of the

final torque reported in Table 3. For a better

performance of the joint, tight again all bolts

once the installation is started up.

Removal of valves welded to the line

Shall the valve need to be removed from the

line, cut the pipe far from the welding point so

that the valve’s gauge can be restored.

Disassembling of the disc

1. In order to remove the disc, the actuator

and the counterweight have to be previously

removed.

2. Remove the bolts between the body and the

bonnet (11). Place them in a clean space.

3. Lift the bonnet (6) by means of a strip and a

hoist and hold it to the eyebolt.

4. Hold the hinge pin and the disc together

(45-3). Place the strip between the hinge pin

and the disc and hold it by means of a hoist.

5. Remove the gland bolts (16), the gland

flange (10), and the gland (9) from the side

of the actuator and from the side of the

counterweight (if existing).

6. Remove the packing by means of an iron

hook-shaped thread.

7. Remove the pin (49) always from the side

from which the actuator was installed.

During this operation, the spacer (65) will be

removed and saved for reassembling.

8. Remove the hinge pin/disc from the valve.

WARNING

The packing assembling must be done without

pressure in the valve and in the line.

7. Tighten the gland bolts gradually and

uniformly, the torque valves can be

calculated according to table 4. For some

alternative days, especially during start up,

re-tighten the bolts in order to repristine the

loosening of the gland.

Actuator assembling
