VT-VRPA1-537-10/V0/QV-RT

VT-VRPA1-537-10/V0/QV-RT由于電磁鐵推力的限制，在大于63L/min的液壓系統中，一般不再選用直推式的電磁換向閥，而選用通過流量較大的電液換向閥。電液換向閥的原理是：控制油通過電磁先導閥到達電液閥主閥芯的兩端（即電液換向閥主閥體兩端蓋側）T6D-038-2R00-C1

，通過電磁先導閥的換向，來實現主閥芯的左右移動，從而開通或切斷通往執行元件的油路，使執行元件運行或停止。但在打開或切斷油路的瞬間，系統中會產生相當大的沖擊，這種沖擊會極大影響液壓系統中液壓元件和密封件的使用壽命。為了減小及至消除由此引起的液壓沖擊，*簡單的辦法是在該電液閥下面疊加一個P口節流閥或進油節流3DREPE6B-2X-25EG24N9K31/F1M-00
