V4系列 Flotect®叶片流量开关

W.E.ANDERSON V4系列 Flotect®流量开关坚固可靠,是自动保护设备和管道系统免受流量减少或损失的理想方法。时间测试在世界各地的数千个管道安装和加工厂,这个系列是耐候的,旨在满足NEMA 4和防爆(清单包括在规格)。本系列产品可用于管道1-1/2“(38.10 mm)及以上。
从棒材中加工的防漏阀体。
选择为您的应用程序校准的定制叶片,V4型,或场可调多层叶片,V4-2-U型(见设定点图)。
使用螺纹、三通或法兰直接和容易地安装到管道中(见应用程序图)。
可用于管道1-1/2“及以上。
电气组件可以很容易地更换,而不需要从安装中拆卸,这样就不需要关闭该过程。
独特的磁驱动开关设计提供卓越的性能。
其特点是一个自由摆动的叶片吸引一个磁铁在固体金属开关体内,通过一个没有波纹管、弹簧或密封件的简单的杠杆臂来驱动一个快速开关。
