Product Bulletin PB-CE-BT200-B July, 2014 BT200 Butterfly Valve SCORE BT200 双偏芯蝶阀 Double-offset Butterfly Valve 应用 Application SCORE 的 BT200 系列双偏芯蝶阀具有阀板面偏离轴平面 Offset1 阀体和阀板的几何中心偏离阀板回 转中心 Offset2 的双重偏芯 阀板与阀座独特的动态密封设计 具有优良的切断性能和耐久性 适用于低压 常温流体的可靠切断和调节 BT200 是软密封 对夹式高性能蝶阀 如需要金属密封 双法兰式阀体 更高的压力等级时请选择 SCORE 的三偏芯蝶阀 BT300/BT320 SCORE the type BT200 double-offset butterfly valve, shaft offsets are created by designing the valve with the shaft located behind the centerline of the sealing surface and slightly to one side of the pipe centerline. Disc and seat are dynamic seals that provides excellent shutoff and high durability, it can be used for a variety of throttling and on-off applications in low pressure (ANSI 150#) and normal temperature. BT200 is a high-performance butterfly valve with soft seal seat and wafer type body, if metal seal seat, double flanged body and more high pressure rating are demanded, pls choose BT300/BT320 triple-offset butterfly valve. 特点 Features 经济严密的切断 流体压力辅助密封的双偏芯设计 提供 了全公称压力下的可靠切断 卓越的流体控制性能 固有特性为近似等百分比 BT200 在 70 度或者 90 度额定开度下均可用于节流调节 维护方便 安装于阀体上的阀座易于装拆 维护性能更好 定制的软阀座 圣戈班 Saint-Gobain 设计 定制的 SG 型软阀座适用温度 压力范围广泛 阀体结构允许材质符合 NACE0175-2003 详情请与 SCORE 联系 可选高性能的 Saint-Gobain GF TFE 填料 Pillar 编织型填料 或 Garlock 柔性石墨填料 EVSP9000 加上动态补偿碟簧 Live-loading 大大降低了阀门填料函逸散泄漏的可能 可符合 API-622 低逸散规范 Economical Tight Shutoff The pressure-assisted seal and double-offset design provides tight shutoff against the full pressure rating of the specified valve.
