2FRM16-3X/160LB
Rexroth
R900424902
用于底板安装。
油口布置符合DIN 24340 G型及ISO 6263。
机械驱动。
可选压力补偿器行程限制。
减小启动阶跃。
通过整流叠加板，实现双向流量控制。
2FRM 型流量控制阀为二通流量控制阀，用于保持恒定流量，其流量基本不受压力和温度影响。
阀通常由阀体（1）、节流孔套（2）、可选带行程限制（3.1）的压力补偿器（3）、单向阀（4）、2FRM 型的调节元件（5），以及齿条活塞驱动装置（6）和换向阀（7）组成。从通道 A 至通道 B 的油流在节流点（9）处被节流。2FRM 型的节流截面通过调节元件（5）机械旋转曲线螺栓（10）设定。调节速度可通过节流单向阀（6.3 和 6.4）设定。为限定所需调节范围，齿条活塞驱动装置（6）的两侧均设有可调行程限制（6.1 和 6.2）。上游设置压力补偿器（3），以确保节流点（9）处的流量恒定且不受压力影响。
节流点的孔口设计使流量基本不受温度影响。
由B通道至A通道的自由回流，经单向阀（4）通过。
受控流量仅由A通道流向B通道。
对于往复流动（正向与回流），可在流量控制阀下方安装 Z4S 型整流叠加板。

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) | ||||
