鑄鋼截止閥產品概述
法蘭鑄鋼截止閥產品由于開閉過程中密封面之間摩擦力小,比較耐用,開啟高度不大,制造容易,維修方便,不僅適用于中低壓,而且適用于高壓。法蘭鑄鋼截止閥可以適用425°C以下石油、化工、制藥、化肥、電力行業等各種的工況上,截斷或接通調節管路介質,還可以改變閥瓣的設計,做節流閥或者調節閥使用。鑄鋼截止閥特點
1、產品結構合理、密封可靠 ;2、密封面堆焊Co基硬質合金,耐磨、耐腐、抗摩擦性能好、使用壽命長 ;
3、閥桿調質及表面氮化處理,有良好的抗腐和抗摩擦性能 ;
4、零件材質及法蘭、堆焊端尺寸可根據實際工況或用戶要求合理選配,滿足各種工程需要;
5、閥芯可根據需要做承切斷型和調節型。
