BUTTERFLY VALVE LUG TYPE PN 6-10-16

Before to assemble the valve at the pipeline, open it turing the

butterfly until half-stroke. Check inside the body to be completely

clean, possible extraneous matters have to be removed in order to

ensure a right functioning. If compressed air is at your disposal, use it

for a better cleaning.

The counter-flanges to have aligned holes, to be parallel and allow

a comfortable insertion of the valve.

Employing welding neck counter-flanges the valve can reach the

PN; otherwise, using slip-on counter-flanges, the sealing values are

lower. Anyway, make sure that the disc (butterfly) can turn free

without touching the counter-flanges.

At installing phase, keep disc (butterfly) semi-open paying attention

that the disc itself doesn’t hit the counter-flanges. Once positioned

the valve, centre the body and insert all the tie-rods nuts or the bolts

nuts maintaining a diametrically opposed sequence (for a better

deformation of the liner).

The sole possible leakage is the non-sealing of the seat, due to a wrong

assembling of the valve at the pipeline with butterfly closed, at the wear of time

of the gasket or to a possible extraneous matters in the pipeline.

Considering the low cost of the valve and the laboriousness of the liner (4)

replacement, this operation is economically advised only for nig diameters and

however it has to be done at a factory in order to test adequately the valve once

repaired, with appropriate equipments.

SEDIMENT COLLECTING STRAINER PN 16

Before to assemble the strainer at the pipeline check inside the body

to be completely clean, possible extraneous matters have to be

removed in order to ensure a right filtering.

The strainer must be assembled following the direction indicated by

the arrow on the body, with flow direction down to up too.

The counter-flanges of the pipeline must be parallel and have

aligned holes. Check the space between them, keeping into

account the gaskets and their flattering after bolts closing (it should

not be too much or too litter) and face to face tolerances as per

EN-558-1 standard.

Fix the strainer in the right position at the pipeline and remember to

insert the gaskets between the flanges centering them as much as

possible on the raised faces.

The raised faces have to be clean to allow a correct tightness.

Fit the bolts in flanges holes and tighten them maintaining a

diametrically opposed sequence (for a better deformation of the

gaskets).

The strainer is normally assembled at pipelines in order to avoid the impurities

to damage the equipment installed below, that is on/off valves, regulating

valves, etc.

The screen (2) has to be periodically cleaned. To carry out this operation:

loosen the body/cover screws (3), take off the cover (4),clean the screen.

Before to assemble it again, check if the sealing areas are carefully cleaned

and not damaged; check if each part of the gasket is integral, otherwise it is

recommended to replace it. If necessary the strainer can be completely

disassembled using standard tools.

If the gate valve should leak from the seat, do not insist in closing with more

strength by the hand wheel and do not use levers because it is possible to

damage more the sealing seats; in this case open and close again the valve

in order to remove possible sediments.

If necessary the gate valve can be completely disassembled using standard

tools.

Before to assemble it again, open the valve at two hand wheel turns, check if

the sealing seats are carefully clean and not damaged; check if each part of

Before to assemble the valve at the pipeline, open it until about




cleaning.





EN-558-1 standard.

The valve must be assembled following the direction indicated by

the arrow on the body. Fix the valve in the right position at the

pipeline and remember to insert the gaskets between the flanges

centering them as much as possible on the raised face.






THIS KIND OF VALVE NEEDS NO MAINTENANCE SINCE THE BELLOWS

HAS BEEN TESTED FOR THOUSANDS MANOEUVRES.

The leakage of fluid from the stuffing box indicate the accidental breaking of the

bellows (6). Waiting to repair or replace the valve, tighten the gland(9).

In order to add more packing when plant not in pressure neither temperature,

unscrew the gland (9), fit new packing and tighten it again.

Using the backseat it is possible to add more packing when the plant is working,

unfasten completely the locking set screw(21) and the rise limiter(22) (if proved),

use the backseat on the stem forcing the opening maneuver, check its

functionality and act following the above mentioned operations. This must be

carried out within a short term from the bellows breaking since the fluid could

damage the functionality of the backseat.

If necessary the valve can be completely disassembled using standard tools.

It is economically advisable to repair the valve only for big sizes.

Before to assemble it again, open the valve at two hand-wheel turns, check if the

sealing seats are carefully clean and not damaged; check if each part of the

gaskets(7-8) is integral, otherwise it is recommended to replace them.

Functioning instructions are supplied together with each valve.

DISC CHECK WAFER VALVE PN 16





The counter-flanges of the pipeline must be parallel and aligned

holes. Check the space between them, keeping into account the

gaskets and their flattering after nuts closing.

Do not weld any flange at the pipeline when the valve is already

assembled.

Fit the tie-rods in flanges holes, necessarily welding neck type, and

tighten them maintaining a diametrically opposed sequence (for a

better deformation of the O-rings).

The non sealing of the disc seat is exclusively due to the wear of time or to

possible extraneous matters in the pipeline.

If the non sealing is due to impurities in the pipeline, deposited on the seats,

disassemble the valve from the plant and remove them.

Due to its shape it is not advisable to disassemble the valve to repair the

sealing seats, in case they are damaged; therefore it is necessary to repair

the valve at a factory, in order to check again the valve once repaired by

appropriate machineries.
