波纹管截止阀特性：一、双重的密封设计(波纹管+填料)若波纹管失效，阀 杆填料也会避免注册,并符合国际密封标准                          二、没有流体损失，降低能源损失，提高工厂设备安 全。                                                                三、使用寿命长，减少维修次数，降低经营成本。四、坚固耐用的波纹管密封设计，保证阀杆的零泄漏，提供无需维护的条件。伍、气体介质阀座采用PTFE软密封材料提高本阀的密封性。六、耐高温≤425℃阀座采用锥面硬密封。达到气密性能零泄漏。设计与制造标准：●设计与制造：BS1873　BS5160　GB12233●法兰尺寸：ANSIB16.5　JB/T79　GB9113●压力温度：ANSIB16.34●结构长度：GB12221●对焊连接尺寸：GB1224●检验与实验：GB/T13927 安装尺寸及重量：GB 1.6MPaDN101520253240506580100125150200L130130150160190200230290310350400480600H230230275295305355410445480525545615780D0120120140160160200240280320360400400450Wt3.55791216243041569098170GB2.5MPaDN101520253240506580100125150200L130130150160190200230290310350400480600H230230275295305355410445480525545615780D0120120140160160200240280320360400400450Wt3.55791216243041569098170GB 4.0MPaDN101520253240506580100L130130150160190200230290310350H230230275295305355410445480525D0120120140160160200240280320360Wt4.9579151724304258
