2FREX 10 B-1X/70L1G24-25N9Z4MM
Rexroth
0811403013
NG6及NG10规格的直动式流量控制阀。
液压油口的分配决定二通或三通功能；三通时剩余流量经P口（第三通路）流出。“NO”常开机能仅能实现二通功能。
通过电磁铁电流进行调节。
用于底板安装，油口布置符合ISO 4401。

3(2)FREX 型不带位置控制的比例流量阀提供规格 6 和 10，采用比例电磁铁操作，滞环 < 5 %。阀用放大器电子装置可选不同结构。“NO”（常开）机能只能用作二通流量阀，即 2FREX 型；“NC”（常闭）机能可用作三通或二通流量阀。由于阀体结构所限，三通型的剩余流量经 P 口导出。二通型的流路为 A 至 B，P、T 口封闭。
