WE04系列两件式法兰不锈钢球阀
150#ANSI法兰、通风球、电动或气动执行机构
WE04系列采用了一个全流道2件法兰不锈钢球阀,以最小的压降实现大流量。该阀门的特点是防喷阀杆可增加安全性,加强PTFE阀座和密封可延长使用寿命,316 SS(ASTM CF8M)球阀可提高性能。执行机构直接安装,为狭小空间提供紧凑的组件。限位开关可直接安装在阀门上,以实现远程位置指示。
WE04系列可配置气动或电动执行机构。电动执行机构有防风雨或防爆、多种电源电压和双位或调制控制。两位执行器使用电源电压驱动阀门打开或关闭,而调制执行器接受4至20 mA的阀门定位输入。热过载保护和齿轮传动装置具有永久润滑功能。
气动双作用执行机构使用气源驱动阀门打开和关闭。致动器有两个供油口,一个驱动阀门打开,另一个驱动阀门关闭。弹簧复位气动执行器使用气源打开阀门,内部加载的弹簧将阀门复位至关闭位置。SN电磁阀也可用于在供气口之间电动切换供气压力,以打开和关闭阀门。执行机构由阳极氧化和环氧涂层铝制成,可提供多年的无腐蚀服务。
