Rugged and compact in design, these valves are manufactured to the latest international designs usingadvanced manufacturing techniques and stringent quality control checks. The valves are regularly supplied to major Indianand international clients including oil refining companies and EPC contractors. They are available in a range of sizes startingfrom 1/4” to 2” (in reduced-bore design) and from 3/8” to 11/2” (in full-bore design).
