ASCO美國3通高流量直動式電磁閥主要參數(shù)  

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
