力士乐双级比例方向节流阀优惠价 力士乐Rexroth双级比例方向节流阀有如下特点:(1)采用没有零位死区且带阀芯位置闭环的六通径伺服比例阀作为先导级,静动态特性优异;(2)当电磁铁失电时,先导阀进入作为“故障保险”的第4位,主阀芯两端卸压,在对中平衡弹簧作用下,处于中位;(3)主阀芯位置用另一个位移传感器控制(双级电反馈),主阀芯闭环叠加在先导阀芯位置闭环上,进一步增强了控制精度和运行的可靠性;(4)主阀芯中带有防阀芯自转(由非全周阀口引起)的插销,能获得很好的可再现性和很高的工作极限;(5)主阀芯上备有负载压力引出口:为了与定位减压门配合实现负载压力补偿,10通径阀中用一个梭阀引出负载压力;16、25通径阀中,负载压力通过两个附加的阀口C1和C2引出;(6)其他可选功能有非对称阀芯、中位泄漏油排泄等。 力士乐Rexroth双级比例方向节流阀的部分*型号: R900937980 FE 16 C-2X/140LK4M R900966626 FE 16 C-2X/140QK4M R900937981 FE 16 C-2X/190LK4M R900937982 FE 16 C-2X/50LK4M R900937983 FE 16 C-2X/80LK4M R900954413 FEE 16 C-2X/190LK0B1M R900746149 FEE 16 C-2X/190LK0G1M R928018808 FEF 0 P10-F00 R928018813 FEF 1 H10XL-F00 R928025383 FEF 1 H3XL-F00 R928018811 FEF 1 P10-F00 R928018812 FEF 1 P25-F00 R900700837 FES 25 CA-3X/200QK4M R900979357 FES 25 CA-3X/315LK4M R900704611 FES 25 CA-3X/315LK4M-1 R901038331 FES 25 CC-3X/315LK4M-1 R900784270 FES 32 CA-3X/280QK4M-5 R900979358 FES 32 CA-3X/450LK4M R900979359 FES 40 CA-3X/670LK4M R900769631 FES 40 CA-3X/670LK4M-3 R900979360 FES 50 CA-3X/1400LK4M R900979361 FES 63 CA-3X/1800LK4M 力士乐双级比例方向节流阀优惠价 R900973604 FESE 25 CA-3X/315LK0B1M R900767349 FESE 25 CA-3X/315LK0B1M=LB R900702016 FESE 25 CA-3X/315LK0B1M-1 R900706964 FESE 25 CA-3X/315LK0G1M R900705160 FESE 25 CC-3X/315LK0B1M-1 R900973605 FESE 32 CA-3X/450LK0B1M R900714381 FESE 32 CA-3X/450LK0B1M-1 R901033548 FESE 32 CA-3X/450LK0G1M R900973607 FESE 40 CA-3X/670LK0B1M R900706696 FESE 40 CA-3X/670LK0B1M-1 R900701432 FESE 40 CA-3X/670LK0G1M R900954504 FESE 50 CA-3X/1400LK0B1M R900709179 FESE 50 CA-3X/1400LK0G1M R901047747 FESE 50 CA-3X/1400LK0G1V R900954505 FESE 63 CA-3X/1800LK0B1M R900764316 FESE 63 CA-3X/1800LK0G1M 力士乐比例节流阀FES(E)系列,先导式,通径 25 , 32 , 40 , 50 和 63;zui高工作压力315 bar和zui大流量1800 L/min
