Rexroth力士乐比例阀哪里价格好
  德国力士乐REXROTH比例阀一般来说和换向阀一样是滑阀结构，只不过阀芯的换向不是靠电磁铁来推动，而是靠前置级阀输出的液压力来推动，这一点和电液换向阀比较相似，只不过电液换向阀的前置级阀是电磁换向阀，而伺服阀的前置级阀是动态特性比较好的喷嘴挡板阀或射流管阀。

Movement of the spool Rexroth Rexroth proportional valve is proportional solenoid control, pressure or flow proportional to the current output and input. Therefore, the input signals can be used to change the methods of pressure, flow, continuous control. Some of the flow control valve also both magnitude and direction function. Rexroth proportional valve according to the function can be divided into pressure valves, flow valve and valve three categories.

Rexroth proportional valve function can be divided according to proportional flow valves, proportional pressure valve, proportional valve three categories. A structured form of electro-hydraulic proportional valve is mainly divided into two categories: one is the spiral cartridge proportional valve (screwin cartridge proportional valve), and the other is proportional spool valve (spool proportional valve).
