Vickers插裝閥基本是由閥(fa)(fa)芯、閥(fa)(fa)套(tao)、彈簧和(he)密封圈組成。根據用途不同(tong)(tong)分為方向閥(fa)(fa)組件(jian)、壓力閥(fa)(fa)組件(jian)和(he)流量(liang)閥(fa)(fa)組件(jian)。同(tong)(tong)一(yi)通徑的(de)三(san)種組件(jian)安(an)裝(zhuang)尺(chi)寸相同(tong)(tong)，但閥(fa)(fa)芯的(de)結構形式(shi)和(he)閥(fa)(fa)套(tao)座(zuo)直徑不同(tong)(tong)。三(san)種組件(jian)均(jun)有兩個主油口A 和(he)B、一(yi)個控(kong)制口x 。

Vickers插裝閥集成塊(kuai)來代替(ti)故障不斷(duan)、難以(yi)診斷(duan)和(he)維修的動(dong)力傳動(dong)控(kong)制裝(zhuang)置。原有控(kong)制系統有60多個連接管件和(he)19個獨立(li)元件。用來替(ti)代的整體(ti)特(te)制集成塊(kuai)上只有11個管件和(he)17個元件。體(ti)積為12 x 4 x 5立(li)方(fang)英(ying)寸，是原系統所占(zhan)空間的20%。
