vickers換向閥具有多種電磁鐵插(cha)頭和(he)位置(zhi)的(de)組合供選擇，安裝靈活。
威格(ge)士換向閥適用于(yu)多種油液(ye)，無需更換密封件。
vickers超過2000萬次循(xun)環試驗已證實其優秀的疲勞(lao)壽命和持久壽命，使(shi)得機器長期生(sheng)產率高，開工時間更長。

vickers換向閥特性產生比(bi)標(biao)注電(dian)(dian)磁鐵更(geng)加(jia)平穩的換向、因此響應時間(jian)也長。這(zhe)些(xie)時間(jian)受到流(liu)量、壓力、施(shi)加(jia)的電(dian)(dian)磁鐵電(dian)(dian)壓、油液粘度(du)和環境溫度(du)的影響。
正(zheng)確的(de)(de)油液狀態對(dui)于液壓元(yuan)件和系(xi)統的(de)(de)長期有效使用來說(shuo)至關重要(yao)。vickers換向閥的液壓油(you)液必須具有清潔度、材料和添加劑(ji)（用于保護元件(jian)免遭(zao)磨損，提高粘度和清除空(kong)氣(qi)）之間的正(zheng)確平(ping)衡(heng)。
可以迅(xun)速而方便的更換電磁(ci)鐵線圈而不引起液(ye)壓系統漏油。
