產(chǎn)品中心直流式襯膠截止閥
產(chǎn)品型號：J45F46
產(chǎn)品口徑：DN15-350mm
產(chǎn)品壓力：1.6-2.5MPa
產(chǎn)品材質(zhì)：鑄鐵、鑄鋼、不銹鋼
直流式襯膠截止閥具有結(jié)構(gòu)緊湊、啟閉靈活、耐腐蝕性能強(qiáng)，行程短（一般為公稱通經(jīng)1/4）等優(yōu)點(diǎn)。被廣泛應(yīng)用在石油、化工等管路系統(tǒng)中做截斷介質(zhì)用，但塑料襯里的截止閥嚴(yán)禁用做流量調(diào)節(jié)，以免節(jié)流口處產(chǎn)生的高速介質(zhì)流沖蝕破壞密封面。
