High-Performance Butterfly Valve
High-performance butterfly valve is a cast steel body butterfly valve compliant with API 609 standard, designed for high pressure and high temperature applications where standard butterfly valves are insufficient. In double-eccentric (offset) models, the disc separates from the seat immediately upon opening; friction and wear are reduced, and metal-seated valves seal without leakage even at high temperatures.
ASTM A216 WCB cast steel body with AISI 316 / CF8M stainless disc is available in EPDM-seated (Class 150, 1½″–14″) and AISI 316 metal-seated double-eccentric (Class 150 / 300, 2″–12″) wafer models. Additionally, carbon steel double-flanged (ASME 150) and stainless wafer / lug type metal-to-metal seated models are offered.
