Stainless Steel Butterfly Valve
Golden Sunbird Metals’ Stainless Steel Butterfly Valve offers efficient flow control and bubble-tight shutoff for a wide range of industrial piping systems. Designed and manufactured to API 609, ASME B16.34, and ISO 5752 standards, these high-performance valves are available in concentric, double eccentric, and triple eccentric designs, as well as wafer, lug, flanged, and grooved end configurations. Sizes range from 2″ to 72″ with pressure ratings from PN6 to PN40 (Class 150–600). Crafted from premium corrosion-resistant stainless steel (F304, F304L, F316, F316L, CF8, CF8M), the valves feature PTFE, EPDM, NBR, or metal seats, delivering quarter-turn operation, low torque, low pressure drop, and fire-safe performance (API 607). Their compact, low-maintenance design ensures long service life even in demanding corrosive and abrasive environments. Ideal for chemical processing, water treatment, oil & gas, HVAC, food & beverage, and power generation applications, our Stainless Steel Butterfly Valves combine superior durability, reliable sealing, and CE-certified quality to optimize your system performance and minimize downtime.
