  • 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 materials. 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 GROUP . . .

  • Latest achievement of the Group expansion policy, NSSL ITALIA provides the Oil & Gas Industry with the highest quality BALL VALVES. Quality and reliability through a full commitment at all levels give NSSL ITALIA today the potential to conquer a prominent position on the market. A long experienced management supported by a highly skilled team assure our customers the best

    answer to suit their needs. Fast service and a firm concern for quality are the basis of our growth and our constant progress. NSSL ITALIA, fully accredited company, produce valves with advanced technol- ogy, production and testing facilities under a severe quality control system. In-house engineering and design facili-

    ties allow the company to respond promptly to any request for special service applications and re- duce pre-production activity time assuring a timely performance. The production covers a full range of forged steel ball valves floating & trunnion mounted, soft & metal seated, side entry, top entry, and fully welded construction in sizes ranging from ½” through 56” and pressure class from 150 Lbs through 2500 Lbs in full accordance with the relevant industry Standards API 6D & BS 5351 ( BS EN ISO 17292 )

    . . . 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.
