THE BALL VALVES
Promoted by Mr. B.L. Shaw, the NECO GROUP is one of the largest In-
dustrial Groups in India. Among the many activities ( mining, infrastruc-
tures, automotive, etc. ) that count over 12500 employees, Ferrous
Foundry is the core business of the Group where NSSL LIMITED has
taken up manufacture of Industrial Valves in ferrous and non-ferrous
NSSL LIMITED, formerly known as NECO SCHUBERT & SALZER LIMITED,
was established in 1988-89. The Company has modernized their shop
floor facilities by introducing CNC machines, Plasma, MIG & Automatic
sub-arc welding machines, automated testing stands and NDE.s facili-
ties. The Unit, with constant efforts, dedication and with the support of
skilled technical personnel, is now manufacturing valves as large as 48”
in pressure class up to ASME 2500, in Cast Carbon Steel, Stainless Steel
and various Alloy Steels for different applications.
The products are designed and manufactured to the International
Standards such as Gate Valves as per API 600 / ISO-10434, API 6D,
ASME B16.34 and API 603 ; Globe Valves as per BS 1873, ASME
B16.34 ; Swing Check Valves as per BS 1868, API 6D, ASME B16.34.
The system and procedures established in the company have been
audited and certified by DNV to ISO 9001:2000.The Quality System
is additionally crowned by AMERICAN PETROLEUM INSTITUTE for
the use of the API 6D Monogram.
The valves are being used in the Core Sector projects and replace-
ments. The clientele, both in Government and Non-Government
Sectors are very wide. The encouragement extended by the prestig-
ious customers in the field of Oil, Gas, Energy, Fertilizers, Steel Sec-
tors, Power and Nuclear Plants have helped the Unit to develop
and market products which are of import substitute nature, such as
valves for CRYO application, valves for sour applications (NACE),
valves for hydrogen service, oxygen service and CNG service.

. . . THE COMPANY
With a total covered workshop area of 13000
sqm NSSL ITALIA plant operates mainly with
multi-pallets work zones, CNC vertical and
parallel lathes for the machining of bodies,
closures and balls for the complete range.
The shop is equipped with all latest technology
machines, including a vertical lathe Mandelli
1700, first installed in Italy, for components on
valves up to NPS 56”.
Welding process is also performed in-house with
capable resources and qualified procedures in
accordance with EN ISO 15614-1 European
Norms and ASME IX ( SMAW - SAW - GMAW ).
Valves engineering and design is developed in-
house by mechanical engineers of our Technical
Department which integrates the traditional sys-
tem with the latest computerized technology
such as F.E.M. and Solid Works 3D model.
For the production of our ball valves, high quality
forgings and components are purchased from
qualified Italian suppliers and full traceability is
guaranteed by strict quality control procedures.
Subsequent to the machining process, the com-
ponents are dimensionally checked by skilled
personnel in the metrological room, equipped
with three-dimensional control machines
( DEA & COORD3 )
Valves testing area is fully equipped and in conti-
nous growth by means of the highest technology
tools including electronic devices. Test benches
are available for valves up to 56” #1500 for all
configurations. Facilities for gas testing, fugitive
emissions and fire safe testing are also available.
All technicians involved in NDT inspections are
qualified in accordance with EN 473 and certified
by CICPND. ASNT qualification is also available.
The Organization and the activities of the Quality
Department are strictly conducted to estab-
lished operating procedures certified in accor-
dance with ISO 9001:2000. The design is cov-
ered by the API 6D Monogram.
