The range of L182 solenoid valves expands with new AISI 316L stainless steel models The new valves are available with different seals (FPM
- NBR - EPDM) and GAS or NPT ports (3/8" - 1/2" - 3/4" -
1"). They are also available with both spade terminals
coils and flying leads ones.
Further to the notable advantages guaranteed by
stainless steel, among the benefits of this range can be
counted the NSF Compliance (pending)... (to continue)
NEW SOLENOID VALVES L176-L376 SIRAI launches the new models L176 (2/2NC) and L376 (3/2NC) with ports size 1/4", available with either brass or stainless steel body, both with FPM sealing. They flank the current "general purpose solenoid valves" L172 and L372 with port size 1/8", Versions with manual override and/or with 1/4NPT ports size, are available on request.
There are a lot of benefits distinguishing these
solenoid valves: low power absorption, noise reduction,
great reliability and long life guarantee by
constructive solutions that assure the core and plugnut
pole faces protection, and by the square section core
that reduces frictions, fur and the problems due to the
dirty fluids control. The features include the coils
with UL approval and the RoHS compliance....... (continua)
NEW MICRO SOLENOID VALVES CATALOGUE The restyling process of SIRAI®
catalogues, comes to a conclusion with the publication
of the new MICRO SOLENOID VALVES one.
Subdivided by types and accompanied with many drawings
and products’ photographs, the new “MICRO SOLENOID
VALVES” catalogues collects all the information
necessary to select the proper modl suited for different
requirements.
SIRAI®’s micro solenoid valves constitute a specific
response to the growing demand for small size low power
control components, created by the constantly increasing
integration of electronics and industry.
A natural development of the general purpose solenoid
valves, the micro solenoid valves can control a variety
of non-aggressive liquid and gaseous fluids.......

A new standard for vegetaBLE oils
supplier devices
of diesel engines.
The new solenoid valve L340V08G is characterized by a
new forged body with hexagonal connections, and an
optimization of internal passages aimed at a sizeable
improvement of flow rate. It ensures improved
performance up to Δp max 6 bar and allows to work even
at very low ambient temperature (up to -30°C)...

NEW "L
SERIES" BROCHURE Out of the four series of solenoid valves which
characterise the SIRAI® range, those for “general
purposes” (defined as “L SERIES”) represent the history along with
the state of the art range of our products.
The core of this series includes some of the now historical models
of our Company which, for reliability and precision, have become
points of reference for all the companies using solenoid valves of
this type for the realisation of their own equipments.
History, however, is not only for that in the past but is above all,
a path of continuous evolution and improvement.... (to

NEW
BROCHURE FOR "COFFEE MARKET" The passion of SIRAI® for the world
of coffee starts in a distant past.
Many years ago we started to exercise this, designing and
manufacturing a product, the pressure switch, for which we have
become well known and appreciated by espresso coffee machine makers
all over the world.
But the passion which has propelled us does not stop here; during
the course of the years we have developed a family of valves
thinking specifically in order to, together with the pressure switch,
guarantee adequate performance and reliability for the “nobility” of
this product.
The fruits of our work are contained in the new brochure dedicated
to the “coffee market”; a very readable....... (to

excellent ideas for a good espresso
in 1969
SIRAI® started to market its
own pressure switch. A few months later, it launched the version for water temperature
control in espresso coffee machines.
The appreciation of the market has been demonstrated by the
high sales: over 6 million pressure switches sold in 40
years
There have been major developments and
improvements in the espresso coffee machines over this period but
the pressure switch was never a problem, as it revealed itself
suitable for tomorrow’s standards from the very beginning.
SIRAI®’s contribution has been to guarantee over time a
high precision, reliable product in terms of mechanism and materials
while, at the same time, developing valves, ... (to

VALVES WITH TECHNOPOLYMER BODY
In an ever increasing typology of applications, is by now necessary
avoid the oxidation involves any part of plant and instrumentation.
To meet this requirement, SIRAI® has designed a new
solenoid valves series, characterized by the high quality of body
material, made in PPS.
Besides solving definitely the problem of oxidation, these solutions
allow to reduce the limescale.
The choice of an high quality polymer, particularly resistant to
chemical and physical aggressions, allows to use these valves for a
wide range of fluids, including low-pressure steam. PPS, furthermore,
offers... (to continue)

After a careful
analysis, we can consider completed the evaluation phase of all our
products in respect of the restriction of use of hazardous
substances in electrical and electronic equipment, as set out in the
“RoHS Directive” that will take effect on next July.
On the basis of our review and of the declarations that we have
