比例阀采用阀芯阀体结构。伺服阀和伺服比例阀主要应用在闭环控制系统,比例阀的驱动装置是比例电磁铁。伺服阀的驱动装置是力马达或力矩马达.阀体兼作阀套。驱动装置不同.所以近些年出现了比例伺服阀。比例阀一般较高几十Hz,伺服阀中位没有死区,伺服阀对液压油液的要求更高.性能参数不同;否则容易堵塞,用来控制流量和流向,比例阀要求低一些.比例阀有中位死区;比例阀和伺服阀的区别主要体现在以下几点:逐渐向伺服阀靠近,比例换向阀属于比例阀的一种,滞环、中位死区、频宽、过滤精度等特性不同.阀的额定压降不同;比例换向阀具有与普通换向阀相似的中位机能,而比例伺服阀性能介于伺服阀和比例阀之间,因此应用场合不同,伺服阀和伺服比例阀采用阀芯阀套的结构。中位机能种类不同.其它结构的比例阀主要应用在开环控系统及闭环速度控制系统;因为比例阀的性能越来越好;2伺服阀的频响(响应频率)更高。阀芯结构及加工精度不同.伺服阀与比例阀之间的差别并没有严格的规定。,可以高达200Hz左右,需要精过滤才行,而伺服阀中位机能只有O型(Rexroth产品的E型)。力士乐4WRPH/4WRPEH型高频响方向阀的特点:直动式伺服电磁阀NG6,配有控制活塞和钢套,伺服性能可靠;单侧控制,断电时处于4/4fail-safe功能位置;调节电磁铁内置有位置反馈器和位移传感器的电子控制单元(LvdtDC/DC);用于生产和试验设备中的电液调节;力士乐4WRPH/4WRPEH型高频响方向阀的用于阀板安装:安装孔符合ISO4401-03-02-0-94;安装板根据产品目录RC45053(单独订购);力士乐4WRPH/4WRPEH型高频响方向阀的符合DIN43560-AM2标准的线缆插座电磁铁2PPE/M16x1,5,位移传感器4P/Pg7包含在供货范围内,参见产品目录RD08008;外部电子控制单元(单独订购)?适用于标准特性曲线“L”的电气放大器0811405060,参见产品目录RD30041?适用于有拐点的特性曲线“P”的电气放大器40%–0811405065和60%–0811405066力士乐4WRPH/4WRPEH型高频响方向阀的技术特点有:●规格6和10●安装面按DIN24340A型和ISO4401●控制流量的方向和大小●用于位置、速度和压力的闭环控制●通过控制电磁铁触发●通过感应位置检测器对控制滑阀进行位置传感●集成电控器(OBE),用于4WRPEH●特性曲线带或不带变化。力士乐伺服电磁阀,带电气位置反馈((LvdtDC/DC)、(耐震设计):4WRPH6、4WRPH10原装进口力士乐REXROTH伺服比例换向阀4WRPEH6***B40L-2X/G24K0/A1M用于位置、速度和压力的闭环控制高频响方向阀正遮盖,直动式,带电位反馈单边驱动,断电时处于四位四通的***位置带有控制活塞,具有伺服功能控制电磁铁带有集成位置反馈和用于位置传感器的电子线路通过控制电磁铁触发控制流量的方向和大小通过感应位置检测器对控制滑阀进行位置控制4WRPEH6***B40L-2X/G24K0/A1M性能好!材料订货号SN:0811404613内置集成式电子放大板(OBE)产品规格大小6mm公称流量40L/min较大流量40L/min公称供电电压24VDC较高工作压:油口P.A.B为315bar,油口T为250bar带钢套的直接操作的滑阀特性曲线带或不带变化底板安装,安装孔结构,安装面按DIN24340A型和ISO44014WRPEH6C3B12L-20/G24KO/A1MD1FVE02BCVFOA40D31FTE01C***NF004WRPEH6***B04L-2X/G24K0/A1M,08114046104WRPEH6***B12L-2XG24K0/A1M,08114046114WRPEH6***B24L-2X/G24K0/A1M,08114046124WRPEH6***B40L-2X/G24K0/A1M,08114046134WRPEH6***B25P-2X/G24K0/A1M,08114046464WRPEH6***B40L-2X/G24K0/F1V,R9011368614WRPH10C3B100L-2X/G24Z4/M,08114040594WRPH10C3B100P-2X/G24Z4/M,08114040634WRPH10***B100L-2X/G24Z4/M,08114040614WRPH10***B100P-2X/G24Z4/M,08114040654WRPH6***B25P-2X/G24Z4/M,08114040454WRPH6***B40L-2X/G24Z4/M,0811A040394WRPH6***B40P-2X/G24Z4/M,08114040464WRPE10E50SJ-2X/G24K0/A1M,08114047704WRPE10E80SJ-2X/G24K0/A1M,08114047714WRPE10EA50SJ-2X/G24K0/A1M,08114047514WRPE10EA80SJ-2X/G24K0/A1M,08114047504WRPE10W50SJ-2X/G24K0/A1M,08114047724WRPE6E18SJ-2X/G24K0/A1M,08114041404WRPE6E32SJ-2X/G24K0/A1M,08114041414WRPE6W32SJ-2X/G24K0/A1M,0811A041434WRPEH10C3B100L-2X/G24K0/A1M,08114048014WRPEH10C3***L-2X/G24K0/A1M,08114048004WRPEH10***B100L-2X/G24K0/A1M,08114048034WRPEH6CB04L-2X/G24K0/A1M,08114047414WRPEH6CB24L-2X/G24K0/A1M,08114043554WRPEH6C3B02L-2X/G24K0/F1M,08114045264WRPEH6C3B04L-2X/G24K0/A1M,08114046004WRPEH6C3B24L-2X/G24K0/A1M,08114046024WRPEH6C3B25P-2X/G24K0/A1M,081140464308114047014WRLE10E1-80SJ-3X/G24K0/A1M08114047004WRLE10E80SJ-3X/G24K0/A1M08114047034WRLE10W1-80SJ-3X/G24K0/A1M08114047024WRLE10W80SJ-3X/G24K0/A1M08114047704WRPE10E50SJ-2X/G24K0/A1M08114047714WRPE10E80SJ-2X/G24K0/A1M08114047514WRPE10EA50SJ-2X/G24K0/A1M08114047504WRPE10EA80SJ-2X/G24K0/A1M08114047724WRPE10W50SJ-2X/G24K0/A1M08114041404WRPE6E18SJ-2X/G24K0/A1M08114041414WRPE6E32SJ-2X/G24K0/A1M0811A041434WRPE6W32SJ-2X/G24K0/A1M0811A040394WRPH6***B40L-2X/G24Z4/MR9005582024WRSE10E1-80-3X/G24K0/A1VR9005791404WRSE10V1-50-3X/G24K0/A1VR9005568124WRSE10V1-80-3X/G24K0/A1VR9009111514WRSE6E10-3X/G24K0/A1VR9009189514WRSE6E1-35-3X/G24K0/A1VR9009061554WRSE6V1-20-3X/G24K0/A1VR9009047944WRSE6V1-35-3X/G24K0/A1VR9002486404WRZE10EA85-7X/6EG24EK31/A1D3MR9009546504WRZE10W6-85-7X/6EG24ETK31/A1D3MR9009608354WRZE16E1-150-7X/6EG24N9K31/A1VR9009546654WRZE16W6150-7X/6EG24K31/A1MR9009779274WRZE16W6-150-7X/6EG24N9ETK31/A1MR9007576054WRZE16W8-150-7X/6EG24N9EK31/F1D3MR9009546784WRZE25W8-325-7X/6EG24ETK31/A1D3MR9007539934WRZE25W8-325-7X/6EG24N9EK31/F1D3MR9013367975-4WE10D5X/EG24K4QMBG24/MR9013373285-4WE10D5X/EG24N9K4QMBG24/MR9013309385-4WE10U10B5X/EG24K4QM0G24/MR9013249705-4WE10X84-5X/EG24K4QMAG24/MR910999932A10VSO18DFR1/31R-VPA12R910991846A10VSO18DFR1/31R-VPA12N00R902459823A10VSO18DFR1/31R-VUC12N00R900590646DB10-2-5X/100R900587772DB10-2-5X/200R900590334DB10-2-5X/315R900599564DB20-1-5X/315XR900589433DB20-2-5X/100R900590768DB20-2-5X/200R900593530DB20-2-5X/315R900423891DBDH10K1X/100R900424147DBDS10K1X/100R900424149DBDS10K1X/200R900420276DBDS10K1X/25R900424150DBDS10K1X/315R900424152DBDS10K1X/400R900424153DBDS10K1X/50R900954707DBEME10-5X/100YG24K31MR900954708DBEME10-5X/200YG24K31MR900536812DBEME10-5X/315YG24K31MR900536813DBEME20-5X/315YG24K31MR900954710DBEME20-5X/350YG24K31MR901065548DBET-6X/200YG24K4VR901065546DBET-6X/350YG24K4VR901000842DBET-6X/50G24K4VR901065545DBET-6X/50YG24K4V)
