止回閥:不銹鋼、雙相鋼、碳鋼、鈦、鎳等材質(zhì) 埃尼斯集團(tuán)生產(chǎn)的美標(biāo)鍛鋼止回閥導(dǎo)向筋上堆焊硬質(zhì)合金閥體上腔導(dǎo)向套采用不銹鋼材料制成保證閥瓣動(dòng)作靈活；閥瓣與閥座密封面采用鈷基硬質(zhì)合金等離子噴焊而成硬度高、抗沖蝕、經(jīng)久耐用；先進(jìn)的壓力密封設(shè)計(jì)和高純石墨墊片環(huán)以確保高氣密；閥門中腔采用壓力自緊式密封結(jié)構(gòu)，內(nèi)腔壓力越高密封性能越好；閥瓣圍繞閥座外的銷軸旋轉(zhuǎn)，減少關(guān)閉時(shí)發(fā)生的猛烈沖擊。
