style="text-indent:25px">閥門主要適用于火力電站各種系統(tǒng)的管路上，切斷或接通管路介質(zhì)。適用介質(zhì)：水、蒸氣等非腐蝕性介質(zhì)。鍛鋼閥門與其他閥門產(chǎn)品相比的特點(diǎn)是高溫高壓，獨(dú)特的自密封設(shè)計(jì)，壓力越高，密封越可靠。由于性能技術(shù)特性、工況的特殊使產(chǎn)品也形成了其他產(chǎn)品所替代不了的特點(diǎn)。上海卓帕真空技術(shù)有限公司座落于浙江溫州永嘉甌北，是一家集科研，生產(chǎn)及銷售鍛鋼閥門的專業(yè)生產(chǎn)產(chǎn)家。公司技術(shù)力量雄厚，設(shè)備精良，工藝先進(jìn)，全部采用現(xiàn)代化精密數(shù)控機(jī)床及各種專業(yè)加工機(jī)器進(jìn)行加工生產(chǎn)，擁有各類加工及檢測(cè)設(shè)備30多臺(tái)，公司通過(guò)了ISO9001認(rèn)證，歡迎大家前來(lái)選購(gòu)產(chǎn)品。真空波紋管價(jià)格</p></p><br
