Rexroth力士樂(lè)比例閥哪里價(jià)格好
  德國(guó)力士樂(lè)REXROTH比例閥一般來(lái)說(shuō)和換向閥一樣是滑閥結(jié)構(gòu)，只不過(guò)閥芯的換向不是靠電磁鐵來(lái)推動(dòng)，而是靠前置級(jí)閥輸出的液壓力來(lái)推動(dòng)，這一點(diǎn)和電液換向閥比較相似，只不過(guò)電液換向閥的前置級(jí)閥是電磁換向閥，而伺服閥的前置級(jí)閥是動(dòng)態(tài)特性比較好的噴嘴擋板閥或射流管閥。

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).
