DR…50B型50系列壓力控制閥是先導式減壓閥，用于系統(tǒng)減壓。

這種減壓閥由主閥體及主閥芯和帶壓力設(shè)定件的先導閥構(gòu)成。

停止時閥開啟，即油從油路B經(jīng)過主閥芯流向油路A，A腔壓力作用在主閥芯底部。同時來自油路A的壓力經(jīng)主閥芯節(jié)流孔并通過孔，作用在先導閥的球形閥芯上。根據(jù)彈簧的設(shè)定值，在球形閥芯前、油路和彈簧腔建立起壓力，控制閥芯在開啟位置。油可以**地從B流向A，直到A腔壓力超過彈簧的設(shè)定壓力，閥芯打開。控制閥芯移動到關(guān)閉位置與A腔壓力與彈簧到達平衡時，就打到了要求的減圧圧力。

控制油總是有彈簧腔經(jīng)油口外泄油。

單向閥用了使油流從油路A**的流回到油路B。

壓力表接口用來連接壓力表以檢測A口二次壓力。
