In the chemical and nuclear plants, in
some services, need a special valves
designed for all dangerous, corrosive,
infiammable, pyrophoric, noxious media
and all category M fluids as per ASME
B31.3 liquid or gas Chlorine (HCI),
Phosgene (COCI2), hydrofluoric acid (HF)
and chloro-fluorinated compounds all
display similar hazards.
Globe valves with metal bellows, welded
to the stem and bonnet, provides a
continuos metallic barrier between the
process fluid and the atmosphere to
achieve zero emission.
The off-shore installations ask for solid
construction valves with different
solutions of materials (Duplex, special
The ball valves in split body, 2 or 3
pieces and the double block and bleed
valves are specific for this kind of
To install valves with high technological
content give us the possibilities to
approach several difficulties application
and develop right product selection
together with customer.
The design sampling system of process
fluids, liquid or gas, individually
designed for the various problems of
analisys, has like objective the supply of
engineered systems according to each
A sampling system properly studied
allows to take a representative sample
of the product, which results in a
excellent accuracy and stable
measurement of the analisys
parameters, as well as in a greater
duration of the analyzers and to an
optimization of maintenance costs.
The butterfly valves have optimal
design for installations on ships (gas
trasnportation and chemical tank,
engine circuits) for the limited weight.
Valves in double or triple eccentric
guarantee long life service.
We have in the time produced the
necessary certifications to such
applications, obtain approvals from
important international companies.
PULP & PAPER
The ball segment valves have an
excellent geometry for the process
control of paper mill. They are used also,
complete with specific actuator, like
basis weight valves. The range of valves
is complete with double eccentric
butterfly valve and slide gate valves, to
full fill, each step of the pulp & paper's
In the gas compression stations are used
high delta-p butterfly valves.
An accurate sizing of each valve's
components (trim, low noise disc,
calibrate disc, etc.) gives the reliable
performance on the process.
