J641H气动截止阀由法兰铸钢截止阀、直行程气缸、电磁阀、限位开关和气源附件等组成的自控阀门系统,气动截止阀是一种依靠压缩空气驱动可实现远距离、大规模集中控制的自控阀门。通常用在需要频繁开闭且要求开闭时间较快的场合,或者是安装不方便人工控制的特殊位置空间,特别适合工艺现场没有电源等驱动源需集中阀门的开闭的工艺管道或者装置中。
1、采用加大型特殊硬化工艺处理的阀杆以适应气动截止阀一般开闭频繁,速度快的工艺特点,防止阀杆弯曲变形失效而减短阀门寿命;
2、可选择单作用气缸 或者双作用气缸以使用不同的工艺要求;
3、选用不同的阀门主体材料可使用于空气、水、蒸汽、油及硝酸、醋酸等对种介质流体;
4、选用防爆电磁阀可用于需要防爆的工作环境;
5、可根据客户要求选用不同的零部件用于特殊工艺环境
