高性能蝶阀遵守美国石油协会（API）609款 B 类规定并能用于开关和节流控制。该类阀门设计用来处理所有通用物料，还包括粘性及腐蚀性液体、腐蚀性气体和蒸汽。多种阀座类型可选，包括可提供双向气密性零泄漏的动态聚四氟乙烯阀座，处理污浊/粘性物料的双层金属/聚四氟乙烯阀座和防火设计的 FyreBlock 阀座，该阀座可满足 API607防火测试标准。符合美国腐蚀工程师协会（NACE）的阀芯、用于逸散型排放控制的阀杆密封选件、适用于低温工况的带压式的阀颈延伸等，可提供多种附件选项。

High Performance Butterfly Valves comply with API 609 Category B and can be used for shutoff and throttling control. They are designed to handle everything from general applications to viscous and corrosive liquids; corrosive gases and steam. A wide variety of seat types are available including the dynamic PTFE seat which provides bubble-tight shutoff in both directions; dual metal/PFE seat for dirty, viscous services; and the Fyre Block seat, designed for fire safe applications, which meets API607 fire test standards. NACE trim, stem seal options for fugitive emissions control, pressurized neck extensions for cryogenic applications, plus many other options are available.
