HAWE哈威PSL比例換向閥-并聯(lián)定量泵系統(tǒng)用的 PSL 型和變量泵系統(tǒng)用的 PSV 型（壓力流量控制模塊 ）的多路換向閥塊有三種規(guī)格可提供。 它用于與負(fù)載無關(guān)的、無級調(diào)節(jié)液壓執(zhí)行元件的運動速度。 多個執(zhí)行元件可以同時和相互無關(guān)地進(jìn)行工作。 這種類型的閥主要用于行走液壓機械（例如：起重控制系統(tǒng)）。 通過選擇執(zhí)行元件 A、B口的各個不同的zui大流量，以及選擇使用各種不同的附加機能（例如：次級限壓、機能關(guān)閉，在基塊內(nèi)、在中間板和附加塊內(nèi)），可以保證*匹配各個控制任務(wù)。
