偏心半球閥
偏心半球閥
半球閥除正常作為全開全閉使用外,也可作調節和節流使用。但要特別注意介質的流動方向,以免密封面受沖蝕或加劇磨損。(料漿閥和煤粉閥嚴禁作調節用)
全焊接鍛鋼固定球閥
全焊接鍛鋼固定球閥
全焊接鍛鋼球閥不會有外部泄漏等現象,閥座是由碳纖維增強特氟隆密封環及碟形簧構成的,球體的加工精度高。閥體材料跟管道材質一樣,不會出現應力不均,密封環本體采用含量20%Carbon(碳素)的RPTFE材質,保障完全無泄漏(0%)。
供熱專用全焊接球閥
供熱專用全焊接球閥
閥門是由全焊接的閥體和增強四氟密封墊組成,閥門可在有雜質及化學物質的情況下進行頻繁操作,運行可靠;適用于區域供熱(熱電聯產)、輸熱、輸油及除氧水等工業管線。
