特点与优点
Features and Benefits
  • 无泄漏,360度径向辐射状均匀负荷,增强弹性材质,使得衬里与阀瓣外表所承受的压力均匀一致,从而确保实现绝对气密性关闭功能
    Non-wetted, 360 degree radially -loaded, elastometric energizer is engineered to provide uniform pressure to the outer circumference of the liner and disc, ensuring absolute bubble tight shut-off
  • 独特的球形阀瓣与衬里,避免经典常规衬里蝶阀容易出现的轴向冷流和变形难题,因此产生可靠、免维护、环保安全的阀杆密封效果
    Unique, spherically-shaped disc and liner eliminates the axial cold flow and deformation problems typical of conventional lined butterfly valves, resulting in a reliable, maintenance-free, environmentally safe stem seal
  • 阀瓣旋转能够轻松适配聚四氟乙烯和其他氟聚合体材料衬里的管道系统,以及其他金属衬里和非金属衬里管道系统,因此在安装过程中,不再需要垫片或衬垫
    The disc swing is compatible with PTFE and other fluoropolymer-lined piping systems as well as other metallic, lined and non-metallic piping systems, resulting in the elimination of spacers during installation
  • 配置ISO 5211标准安装法兰,可以直接安装执行器,不会产生迟滞后果,也避免了其他昂贵的自动化部件
    ISO 5211 mounting flange allows the direct mounting of actuators, eliminating hysteresis and costly automation hardware
  • LBF衬里蝶阀设计结构特征就是球形模铸和机加工、全衬里密封面,采用一系列同轴锯齿技术牢靠的固定在阀体表面,因此减少径向冷流
    LBF design features spherically-molded and machined, wide-liner sealing surfaces that are securely anchored within the faces of the valve body by a series of concentric serrations, resulting in the reduction of radial cold flow
  • 坚固耐用的阀体结构设计,强度和将要连接的法兰规格PN10/16的对接法兰一样坚固,避免产生偏转挠曲问题,改善法兰密封性能
    Robust body construction is designed to be as strong as the PN10/16 counter flanges to which it will fastened - eliminating deflection problems and resulting in improved flange sealing properties
  • 外部采用聚酯聚氨酯粉末涂覆,实现防腐保护作用
    Polyester Polyurethane powder coating for external corrosion protection
  • 特别适用于氯气应用领域
    Ideally suited for chlorine gas service
