D*1FW、D*1FB系列先導(dǎo)式比例換向閥

D*1FW系列采用PWD00A-400功率放大器進(jìn)行電控； 

D*1FB系列采用集成的電子元件插裝在閥上組成一體。 

該閥共有10通徑、16通徑、25通徑、32通徑幾種規(guī)格。應(yīng)用于通過(guò)調(diào)節(jié)斜坡信號(hào)可使閥芯柔和換向，以此來(lái)減小液壓和機(jī)械沖擊，通過(guò)電氣方式調(diào)節(jié)流量/速度可實(shí)現(xiàn)機(jī)械功能的自動(dòng)化。  

特點(diǎn)：  

泄漏量小；  

漸進(jìn)的流量特性使得流量調(diào)節(jié)靈敏；  

彈簧對(duì)中的主級(jí)；  

比例先導(dǎo)；  

安全系統(tǒng)的初始位置監(jiān)控；  

D*1FB系列帶有集成的功率放大器；  

D*1FW帶有數(shù)字式Snap-On功率放大器。
