ASCO美國3通高流量直動式電磁閥主要參數  

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

專為高流量駕駛沒有較限度

所需的操作壓力;例如發電廠,

煉油廠,化學加工

平衡提升機建設高流量在

較功率水平

 聚四氟乙烯車手環和石墨填充密封減少

摩擦和消除粘附提供
