金属硬密封球阀
产品描述
阀门的驱动部分根据阀门结构和用户要求,采用手柄、涡轮、电动、气动等,可根据实际情况和用户要求选择合适的驱动方式。
该系列球阀产品根据介质和管道的情况,以及用户的不同要求,设计防火、防静电等结构,耐高温、耐低温,能保证阀门在不同工况下经常工作,广泛应用于天然气、石油、化工、冶金、城建、环保、制药、食品等行业。
特征
• 该系列阀门采用锻钢或铸钢作为阀体材料。结构可以是浮动式或耳轴式球支撑。
• 高精度加工可实现卓越的球和阀座接口,可实现符合 ANSI B16.104 dass VI 泄漏标准的严密关闭。
• 浮动安装型的流向是单向的。耳轴安装类型是完全双向的,具有双阻塞和排放能力。
• 低操作扭矩的可靠操作:膜片弹簧加载的阀座与球保持紧密接触,即使在低压下也能确保紧密密封。这导致低打开和关闭扭矩。
• 防火:金属阀座和石墨密封的组合确保防火能力。
• 最高服务应用温度高达 550°C (1022° F)。球体和阀座由航天高速覆盖层硬化。并且硬度满足HRC 70-72。
• 端部连接:DIN 或ANSI 法兰、对焊或承插焊。
