POLOVO 电动球阀特点
电动球阀具有旋转的90度动作,球有圆形通孔通过轴线,当球旋转90度时,在进、出口处应全部呈现球面,从而截断流动,反之既呈现通孔,使介质通过。全通径的球体内腔为介质提供了阻力很小、直通的流道。气动执行器快速旋转90度的就能使球阀瞬间关闭严密,执行器与阀体的直接连接减少了发生故障的机率。法兰连接的管路能保持良好密封性能,便于维修更换,便于管路的封闭。 ■防火、防静电设计 ■阀杆防爆出装置 ■阀球上设计有压力平衡孔 ■双层阀杆填料与对压碟型弹片装置
◇电动球阀附件选项
回讯器:也叫限位开关APL210N APL310,远程反馈开关信号(防爆)APL410N
电磁阀:双作用选二位五通、单作用选二位三通(防爆)PLVD5/2
三联件:可对气源稳压、过滤、气缸加润滑油YT-200
手轮机构:转动手轮机构,可实现手动开、关阀
电气定位器:输入4~20mA信号,实现阀门调节功能
备注: 气缸参数请另参考所选配的气动执行器资料
