Caliper Overseas is a trusted Duplex Steel Valves manufacturer and supplier in India provides good quality valves for any type of industrial usage. Duplex Steel Valves are produced by utilizing a unique alloy of ferritic and austenitic stainless steel to provide high strength combined with corrosion resistance. Duplex Steel Valves are available in numerous different types of connections such as welded, socket, clamped, flanged and threaded to suit numerous different systems.
Duplex Steel valves possess elevated strength, higher resistance to pitting, stress corrosion cracking and erosion, thereby well-suited for harsh operating conditions. The valves provide long life, safe sealing and stable operating behavior under high pressure and temperature. The valves are manufactured as per ASTM A351 / A494 and ASME SA351 / SA494 specification to maintain quality and performance.
