ksb凱士比蝶閥設(shè)計規(guī)格：
■半凸緣式閥體（T2）：DN40～600。
■全凸緣式凸面閥體（T4）：DN40~600。
■彈性膠套：通過額外的橡膠作用于閥軸流道部分,利用閥體和蝶板的擠壓形成緊栓效果的閥軸端密封。
■機加工球面的蝶板能保證上下游流道的密封。
■可以拆卸下游管道,閥門關(guān)閉作為管道盲板。
■面對面尺寸標準根據(jù) ISO5752 系列20和EN558 系列20。
■執(zhí)行機構(gòu)連接平臺符合 ISO5211 標準。
■閥門標識符合 EN19 標準。
■根據(jù) EN12266-1/泄漏等級 A 和 ISO5208 等級 A，閥門在流道雙方向關(guān)斷有良好的密封效果(無肉眼可視泄漏）
ksb Kesby butterfly valve design specifications:
■ Semi-flanged valve body (T2): DN40 ～ 600.
■ Full flange convex valve body (T4): DN40 ~ 600.
■ Elastic rubber sleeve: through extra rubber acting on the valve shaft flow channel part, the valve shaft end seal of the plug effect is bed by the extrusion of the valve body and the butterfly plate.
■ Butterfly plate with machined spherical surface can guarantee the sealing of upstream and downstream flow channels.
■ The downstream pipeline can be disassembled, and the valve is closed as a pipeline blind plate.
■ Face-to-face dimensions are based on ISO5752 series 20 and EN558 series 20.
■ Actuator connection platb conbs to ISO5211 standard.
■ Valve identification conbs to EN19 standard.
■ According to EN12266-1 / leakage level A and ISO5208 level A, the valve has a good sealing effect when the flow path is closed in both directions (no visible leakage)
