    產品詳細說明
    DR…50B型50系列壓力控制閥是先導式減壓閥，用于系統減壓。

    這種減壓閥由主閥體及主閥芯和帶壓力設定件的先導閥構成。

    停止時閥開啟，即油從油路B經過主閥芯流向油路A，A腔壓力作用在主閥芯底部。同時來自油路A的壓力經主閥芯節流孔并通過孔，作用在先導閥的球形閥芯上。根據彈簧的設定值，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定壓力，閥芯打開。控制閥芯移動到關閉位置與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。
