進(jìn)口電動(dòng)V型調(diào)節(jié)球閥采用圓柱型彈簧預(yù)載的帶補(bǔ)償性可動(dòng)金屬閥座結(jié)構(gòu)，密封性能可靠。球芯與閥座不會(huì)產(chǎn)生卡阻或脫離，使用壽命長(zhǎng)。
球芯上的V形切口與金屬閥座之間具有剪切作用，特別適用于控制高粘度，含纖維、固體顆粒及漿料等介質(zhì)。結(jié)構(gòu)制造紙工業(yè)的紙漿顯得尤為優(yōu)越。
閥門的流通能力大、壓力損失小、且介質(zhì)不會(huì)沉積在閥體中腔，閥門不僅具有近似等有分比的流量特性、可調(diào)范圍大，可調(diào)比為100：1，還具有精確調(diào)節(jié)與可靠定位的功能。
