Valve Solutions for Corrosive Applications 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 ball, plug, butterfly, diaphragm, ball check, swing check, sampling, sight glass, and Y-strainer valves — alongside complete lined and thermoplastic pipe & fittings ranges, in sizes from 1/2″ to 24″.
Every product is tested 100% before dispatch and shipped to customers across 45+ countries — from the USA and Europe to Latin America, Africa, Russia, South East Asia, and Australia.
