ASCO美国3通高流量直动式电磁阀主要参数

ASCO美国3通高流量直动式电磁阀主要参数  

Designed for high flow piloting with no minimum

operating pressure required; e.g. power plants,

refineries, chemical processing

Balanced Poppet construction for high flow at

minimum power levels

 PTFE rider rings and graphite-filled seals reduce

friction and eliminate sticking to provide

专为高流量驾驶没有较限度

所需的操作压力;例如发电厂，

炼油厂，化学加工

平衡提升机建设高流量在

较功率水平

 聚四氟乙烯车手环和石墨填充密封减少

摩擦和消除粘附提供

的使用寿命

316不锈钢结构的高度

腐蚀性的气氛
