4WE6GA6X/EG24N9K4先導閥的換向

4WE6GA6X/EG24N9K4先導閥的換向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（R900933031 PGH2-1X/008LF07MK0

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式雙單向節流閥、出油節流式雙單向節流閥，以延長閥芯的換向及復位時間，從而到降低液壓沖擊的目的。下面就以彈簧復位型、三DS3-TB23/10N-D24K1黎翔現貨
