halves.

• The half of the gasket for which it is possible

to correctly place all Plug-In® tabs in their

corresponding notches, can be mounted as

described in 5.7.1.

• On the other half, use shears to remove all the

Plug-In® tabs and, if present, all the connecting

bridges between the diagonal and the sealing ring

(Fig.9 b).So, following the procedure described in

point 5.7.3, attach the gasket, excluding the sealing

rings.

1. Models equipped with Plug-In® tabs inside the

sealing rings: using shears, cut the Plug-In® tabs

inside the sealing rings (Fig. 9 c) corresponding to

the closed holes only. Then, following the procedure

described in point 5.7.3, attach only the connecting

bridges between the diagonal and the ring.

2. Models without Plug-In® tabs inside the sealing

rings: no cutting is necessary; proceed as described

in point 5.7.1.

NOTE: On some models it might be necessary to

remove all the Plug-In® tabs (not only those inside

the sealing rings). In this case, if permitted, remove

the entire gasket.

A: Leak detector vents

are notches in the

surfaces of the gasket

sections around the

portholes which

vent any leaks to the

atmosphere so that

they can be detected.

tabs and, if present, all the connecting bridges between the

diagonal and the sealing ring (Fig.9 b).So, following the pro-

cedure described in point 5.7.3, attach the gasket, exclud-

ing the sealing rings.

NOTE: For the DN200 models it is recommended, if

permitted, to attach the entire gasket.

5.7.3 - Gluing

• Using the appropriate epoxy glue (supplied as a

spare part, on request), spread a strip of glue (2-3 mm)

onto the plate in the gasket slot.

• Leave to dry for 5 minutes in a suitably ventilated

room, then position the gasket on the plate, making

sure that it is perfectly contained in the slot and that

there is no excess glue escaping from the slot.

• Place a counterweight on the glued plates (without

deforming the plastic), ensuring that the whole gasket is

evenly compressed for at least 2 hours.

N.B. Some particular standards (e.g. ACS Attestation

de Conformité Sanitaire) may prohibit direct contact

between fluid and glue. If this is the case, do not glue

the parts of the gasket which could come into direct

contact with the fluid.

WARNING: Always follow the mandatory general

standards for personal protection, in particular: avoid

contact with the eyes, use an appropriate protective

mask to protect against inhalation hazards and wear

gloves.
