美國派克溢流閥應(yīng)用領(lǐng)域
Parker派克DSD系列NG6溢流閥通過壓力口P的開啟使油液流回油箱來限定系統(tǒng)壓力,。閥NG6為直動式并且有依照DIN-標(biāo)準(zhǔn)的P口,，A口和T口。P口和A口在閥體內(nèi)連通,。該直動式閥也可以被用作先導(dǎo)式溢流閥的先導(dǎo)閥,。Parker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）校準(zhǔn)并頒發(fā)證書,。相應(yīng)的TUV證書隨閥一同供貨。：宋珍
