力士樂雙級比例方向節(jié)流閥優(yōu)惠價(jià) 力士樂Rexroth雙級比例方向節(jié)流閥有如下特點(diǎn):(1)采用沒有零位死區(qū)且?guī)чy芯位置閉環(huán)的六通徑伺服比例閥作為先導(dǎo)級,靜動態(tài)特性優(yōu)異;(2)當(dāng)電磁鐵失電時(shí),先導(dǎo)閥進(jìn)入作為“故障保險(xiǎn)”的第4位,主閥芯兩端卸壓,在對中平衡彈簧作用下,處于中位;(3)主閥芯位置用另一個(gè)位移傳感器控制(雙級電反饋),主閥芯閉環(huán)疊加在先導(dǎo)閥芯位置閉環(huán)上,進(jìn)一步增強(qiáng)了控制精度和運(yùn)行的可靠性;(4)主閥芯中帶有防閥芯自轉(zhuǎn)(由非全周閥口引起)的插銷,能獲得很好的可再現(xiàn)性和很高的工作極限;(5)主閥芯上備有負(fù)載壓力引出口:為了與定位減壓門配合實(shí)現(xiàn)負(fù)載壓力補(bǔ)償,10通徑閥中用一個(gè)梭閥引出負(fù)載壓力;16、25通徑閥中,負(fù)載壓力通過兩個(gè)附加的閥口C1和C2引出;(6)其他可選功能有非對稱閥芯、中位泄漏油排泄等。 力士樂Rexroth雙級比例方向節(jié)流閥的部分*型號: 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 力士樂雙級比例方向節(jié)流閥優(yōu)惠價(jià) 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 力士樂比例節(jié)流閥FES(E)系列,先導(dǎo)式,通徑 25 , 32 , 40 , 50 和 63;zui高工作壓力315 bar和zui大流量1800 L/min
