Giving Corrosion a Tough Time Since 1988
UNP Polyvalves began in 1988 with a single 1,600 sq ft manufacturing plant and a clear mission: solve the corrosion problems that nobody else in India was solving for the chemical and process industries.
Today, our facility spans 210,000+ sq ft with 250+ employees, producing both solid plastic and fluoropolymer-lined valves alongside complete pipe & fittings ranges, in sizes from 1/2″ to 24″.
Every valve is 100% tested before dispatching because corrosion may be unpredictable, but quality shouldn’t be. Today, UNP Polyvalves proudly exports its corrosion-resistant flow control solutions to 45+ countries, including the USA, Europe, Latin America, Africa, Russia, Southeast Asia, and Australia, earning the trust of industries that simply can’t afford second chances.
