ksb凯士比蝶阀设计规格：
■半凸缘式阀体（T2）：DN40～600。
■全凸缘式凸面阀体（T4）：DN40~600。
■弹性胶套：通过额外的橡胶作用于阀轴流道部分,利用阀体和蝶板的挤压形成紧栓效果的阀轴端密封。
■机加工球面的蝶板能保证上下游流道的密封。
■可以拆卸下游管道,阀门关闭作为管道盲板。
■面对面尺寸标准根据 ISO5752 系列20和EN558 系列20。
■执行机构连接平台符合 ISO5211 标准。
■阀门标识符合 EN19 标准。
■根据 EN12266-1/泄漏等级 A 和 ISO5208 等级 A，阀门在流道双方向关断有良好的密封效果(无肉眼可视泄漏）
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 formed 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 platform conforms to ISO5211 standard.
■ Valve identification conforms 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)
