美國(guó)VICKERS電液換向閥，威格士Vickers電磁閥，VICKERS現(xiàn)貨總現(xiàn)貨
VICKERS電磁閥主要用在電氣液壓伺服系統(tǒng)中作為執(zhí)行元件（見(jiàn)液壓伺服系統(tǒng)）。在伺服系統(tǒng)中，液壓執(zhí)行機(jī)構(gòu)同電氣及氣動(dòng)執(zhí)行機(jī)構(gòu)相比，具有快速性好、單位重量輸出功率大、傳動(dòng)平穩(wěn)、抗干擾能力強(qiáng)等特點(diǎn)。另一方面，在伺服系統(tǒng)中傳遞信號(hào)和校正特性時(shí)多用電氣元件。因此，現(xiàn)代高性能的伺服系統(tǒng)也都采用電液方式，伺服閥就是這種系統(tǒng)的必需元件。
