Super duplex butterfly valves are specialized industrial valves made from super duplex stainless steel, offering exceptional corrosion resistance and strength for harsh environments. They feature a disc-shaped closure mechanism that rotates on a central axis for efficient flow control.

Key Features

These valves combine ferritic and austenitic microstructures, providing high resistance to pitting, crevice corrosion, and stress corrosion cracking, especially in chloride-rich settings like seawater or chemicals. They support pressure ratings from 150 to 2500 lbs and sizes from 1/2" to 48" (DN15 to DN1200), with options for manual, pneumatic, or electric actuation. Seals often use PTFE or RPTFE, enabling temperatures from -29°C to +180°C and suitability for water, oil, gas, sewage, and food applications.

Common Grades

Primary material is Super Duplex 2507 (UNS S32750, SAF 2507), with chemical specs including 24-26% Cr, 3-5% Mo, 6-8% Ni, and up to 0.03% C for density around 7.8 g/cm³. Other grades like S32760 appear in similar valves for oil-gas and chemical use.

Duplex butterfly valves are quarter-turn valves made from duplex stainless steel, offering superior strength and corrosion resistance compared to standard stainless steel due to their mixed austenitic-ferrritic microstructure. 

Key Specifications

These valves typically range in size from 1-1/2" to 72" (DN40 to DN1800), with pressure classes like PN10/PN16, Class 150, or up to 600 psi.
Common designs include lug-type, wafer, or flanged ends, with triple offset for zero leakage and compliance to standards like API 609, EN 593, or ISO 5752.
Seats are often EPDM, PTFE, NBR, or metal-to-metal, with manual, pneumatic, or electric actuation.
