J941H美標電動截止閥,電動美標截止閥,用電動執(zhí)行器操作代替手輪手動操作,更符合大型工程的安裝和使用。J941H美標電動截止閥制造按照API600標準,驗收按API598標準,根據(jù)美標標注設計制作,J941H美標電動截止閥無論您是要出口還是內銷,品質同樣保證。
J941H電動美標截止閥特點及主要優(yōu)點:
1) 與閘閥相比,截止閥的結構較簡單,制造與維修都較方便
2) 密封面不易磨損、擦傷,密封性較好,壽命較長
3) 啟閉時閥瓣行程較小,啟閉時間較短,閥門高度較小
1、結構簡單,制造和維修比較方便
2、工作行程小,啟閉時間短
3、密封性好,密封面間磨擦力小,壽命較長
4、在開閉過程中密封面的摩擦力比閘閥小,耐磨
5、通常只有一個密封面,制造工藝好,便于維修
6、截止閥閥體的結構形式有直通式、直流式和直角式
