派克 P直動式減壓閥PRDM系列
簡要描述：
P直動式減壓閥PRDM系列描述：PRDM系列元件為直動式減壓閥。主要用于將液壓系統(tǒng)中的某一支路壓力調節(jié)到系統(tǒng)公稱壓力以下的某一預定值。此外，還將該支路的溢流功能集于一體。壓力表接口或測量接口直接在元件上，以便控制支路壓力。

該閥為常開元件，在設定值以下它允許油液自由地流過控制流道。當下游流道中壓力升高至預調節(jié)的壓力時，閥芯向關閉的方向移動，以減少來自主系統(tǒng)的流量，緩沖柱塞將自行調整，以維持預定的支路系統(tǒng)壓力。當支路系統(tǒng)壓力由于外力作用升高時，緩沖柱塞將克服彈簧力移動并且使大量的油液流回油箱，使壓力不再繼續(xù)升高。
泄漏油通過彈簧腔流回油箱。
