Rexroth
R901087087
三位四通、二位四通或二位三通型式。
标准版本。
油口布置符合DIN 24340 A型。
湿式直流电磁铁。
电磁线圈可旋转。
更换线圈无需打开耐压密封腔。
采用独立电气连接。
隐蔽式手动应急操作。
WE 型换向阀为电磁铁驱动的滑阀式换向阀，用于控制油流的通断及方向。
换向阀主要由阀体（1）、一个或两个电磁铁（2）、控制阀芯（3）以及一个或两个复位弹簧（4）组成。断电时，复位弹簧（4）使阀芯（3）保持在中位或初始位置，阀芯由湿式电磁铁（2）驱动。
为确保正常功能，必须使电磁铁的耐压腔充满油液！
电磁铁（2）的力经推杆（5）作用于控制阀芯（3），将其从静止位置推至所需端位，从而接通符号所示流向。电磁铁（2）失电后，复位弹簧（4）将阀芯（3）推回静止位置。
手动应急操作（6）可在电磁铁未通电时移动控制阀芯（3）。

Important information on hydraulic fluids! For further information and data on the use of other hydraulic fluids, please refer to data sheet 90220 or contact us! There may be limitations regarding the technical valve data (temperature, pressure range, life cycle, maintenance intervals, etc.)! The flash point of the hydraulic fluid used must be 40 K higher than the maximum solenoid surface temperature. Flame-resistant – containing water: Maximum pressure differential per control edge 50 bar. Pressure pre-loading at the tank port >20% of the pressure differential; otherwise, increased cavitation Life cycle compared to operation with mineral oil HL, HLP 50 to 100 % Bio-degradable: When using bio-degradable hydraulic fluids that are zinc-solving, zinc may accumulate in the fluid (700 mg zinc per pole tube) | ||||
注意事项！
仅可使用圆头工具 (Ø3+1 mm) 或专用工具（需单独订购，物料号 R900024943）操作手动应急装置！
仅当油箱压力不超过 50 bar 时，才能进行手动应急操作。
手动应急操作装置锁定时，必须防止电磁铁通电！
必须防止电磁铁同时通电！
电气连接时，应按规定连接保护接地导线（PE，接地）。
