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(dǎo)式比例壓力閥典型的應(yīng)用在：夾緊壓力系統(tǒng)，試驗(yàn)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(jié)構(gòu)：溢流閥由帶閥芯的主級(jí)和先導(dǎo)級(jí)所組成。在先導(dǎo)級(jí)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(diào)節(jié)的給定值進(jìn)行無級(jí)的調(diào)節(jié)。
電磁鐵將電流轉(zhuǎn)換成作用在先導(dǎo)級(jí)閥錐上的力。VMY*L的結(jié)構(gòu)：減壓閥由帶閥芯的主級(jí)和先導(dǎo)級(jí)所組成。
派克DSDU系列先導(dǎo)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(jié)構(gòu)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(jīng)過TUV（德國技術(shù)監(jiān)控協(xié)會(huì)）校準(zhǔn)并頒發(fā)證書。相應(yīng)的TUV證書隨閥一同供貨
