現(xiàn)貨美國PARKER派克D31FHE02C1NB0044比例壓力控制閥

派克VBY*L/VMY*L系列先導式比例壓力閥典型的應用在：夾緊壓力系統(tǒng)，試驗和檢測裝置或重量平衡系統(tǒng)之中。同樣也可以在閉環(huán)壓力控制回路中使用。VBY*L的結構：溢流閥由帶閥芯的主級和先導級所組成。在先導級上有控制油噴嘴和阻尼孔。
所要求的zui高的系統(tǒng)壓力可以在電子放大板上按照所調節(jié)的給定值進行無級的調節(jié)。
電磁鐵將電流轉換成作用在先導級閥錐上的力。VMY*L的結構：減壓閥由帶閥芯的主級和先導級所組成。
派克DSDU系列先導式溢流閥通過壓力口的開啟使油液流回油箱來限定系統(tǒng)壓力。該結構系列的閥有平穩(wěn)的流量-壓力特性曲線，用于蓄能器系統(tǒng)安全。該類閥經過TUV（德國技術監(jiān)控協(xié)會）校準并頒發(fā)證書。相應的TUV證書隨閥一同供貨
