這些閥組合了先導(dǎo)輔控式平衡閥和經(jīng)C3端口進行制動的梭閥的功能;它們能用在兩側(cè)等截面、并帶有超限負(fù)載和彈簧加載保持制動功能(典型的設(shè)備，是由液壓馬達驅(qū)動的絞盤)的執(zhí)行器上。

　　在絞盤回路中，當(dāng)負(fù)載下降時，由超限負(fù)載所引起的壓力保持不變，可將先導(dǎo)比R選得盡可能高，以便加快速度并節(jié)省能量。但考慮到的是，打開平衡閥所需的“先導(dǎo)壓力”，始終“”制動解鎖壓力(一般為15~20bar)。實際上，當(dāng)負(fù)載開始下降時，建立的先導(dǎo)管路壓力達到制動卸荷的壓力設(shè)定值，才能打開平衡閥，并使馬達開始轉(zhuǎn)動。對于液壓馬達而言，打開平衡閥所需的先導(dǎo)壓力值可由以下公式計算得到：
　　Ppil = ( Pt-Pload ) / ( R+1 )
　　低先導(dǎo)壓力(Ppil)為： (Ppilmin)= ( Pt – Ploadmax ) / ( R+1 )
　　這里：
　　Pt = 壓力設(shè)定值(溢流閥設(shè)定)
　　Pload = 負(fù)載所引起的壓力
　　R = 先導(dǎo)比
　　舉例：
　　Ploadmax =170bar ( f負(fù)載所引起壓力的大預(yù)期值)
　　Pt = 325bar (> 1.3*170 bar )
　　R = 8:1 ( 先導(dǎo)比 )
　　制動卸荷壓力 > = 17 bar力士樂 比例閥 武漢 現(xiàn)貨
　　(Ppilmin) = (350-170) / (8+1) bar = 20bar > 17bar
　　由于低先導(dǎo)壓力大于17bar，因此所選的平衡閥，相關(guān)參數(shù)為R=8:1 且Pt=350bar,符合正確的下降順序要求。
　　如果不符合要求，就應(yīng)當(dāng)選擇其它的先導(dǎo)比或壓力值。
