DLHZ0-T-040-L7131/PE ATOS電液比例控制閥                                                                         ATOS電液比例控制閥實(shí)質(zhì)上是一種廉價(jià)的、抗污染性能較好的電液控制閥。比例閥的發(fā)展經(jīng)歷兩條途徑，一是用比例電磁鐵取代傳統(tǒng)液壓閥的手動(dòng)調(diào)節(jié)輸入機(jī)構(gòu)，在傳統(tǒng)液壓閥的基礎(chǔ)下：發(fā)展起來(lái)的各種比例方向、壓力和流量閥；二是一些原電液伺服閥生產(chǎn)廠家在電液伺服閥的基礎(chǔ)上，降低設(shè)計(jì)制造精度后發(fā)展起來(lái)的。                                                                                                                      伺服比例閥DLHZO-T-040-L13
