Established in 1989, NSSL Private Limited has achieved continuous sustainable growth in Industrial Valves and Automotive Components since its inception thanks to the constant efforts put in by dedicated technical staff.
NSSL has two operating divisions - Ferrous Valves and Automotive Machining, each equipped with two production plants for manufacturing operations under controlled guidance. The sophisticated, state-of-the-art modern workshop caters to the diverse needs of our valued customers. We have a Captive Foundry unit regulated with strict quality control measures to help us meet urgent requirements. We adorn our hat with several quality certifications acquired from organisations, including ISO, OHSAS, CE, and API.
NSSL has strong footprints in Europe with the installation of a new, state-of-art manufacturing plant (NSSL Italia S.r.l) in Rotterfeno, Italy, for manufacturing Big Size Ball valves, Plug valves & Gate, Globe & Check Valves.
We have also registered for approvals in major oil-producing countries like Kuwait, SA, Qatar, Oman, Malaysia, UAE, Iran, etc. We have been recognised as a world-class manufacturer worldwide. We have tested cryogenic valves up to 28" 300#. We have the facilities for fire-safe testing, TAT Testing as per Shell Specs, Fugitive Emission Tests, and Certification as per API 624.
We have two dedicated shops for machining different Auto Components. The Auto Machining Division was established in 1998 with only four machines and two types of cylinder heads, namely Ford 2.9L & 4.0L. Our management set up a well-equipped modern machine shop to cater to the demands for cylinder heads in domestic and overseas markets. Our Auto Machining Unit is now one of the most modern state-of-art CNC machine shops with 34 CNC Machining centres with SPMs, Conventional Machines, and an Ultramodern inspection facility like 3D CMM & Trimos.

Our manufacturing plants use conventional and sophisticated CNC Machines for smooth machining and accuracy. The machines are maintained separately with the help of multi-skilled labour to extend their longevity and productivity. We have also deployed new imported CNC machines capable of handling many operations in a single setting for high productivity.
The in-house Spectrometer and Portable Positive Material Identification (PMI) machines help to verify that the right material goes through the incoming stage till the final dispatch. The in-house Calibration facility warrants proper usage of measuring equipment with up-to-date calibration of individual status code. The Valve testing facility is capable of handling more than 1000 valves all at once. The use of dual pressure gauges secures pressure status at all points. Our ferrous valve unit uses heavy-duty EOT cranes with auxiliary hooks, Jib Cranes, and other equipment for efficient material handling.
We have a dedicated R & D team to monitor and implement continuous development activities right from the valve designing stage to ensure higher customer satisfaction.
Every type of valve manufactured in NSSL is validated under the supervision of the R&D Head from the Valve designing stage till it reaches the hands of the customer. The customer's feedback and the design changes are incorporated from time to time to improve the performance of the valves.
