Z41Y forged steel flange gate valve GB, JB
Product Name:
Z41Y forged steel flange gate valve GB, JB
Description:
鍛鋼法蘭閘閥GB、JB Z41Y 

GB、JB鍛鋼法蘭閘閥
Z11\61\41Y-25\40\64\100\160  

GB、JB鍛鋼法蘭閘閥主要設計規范
   設計與制造 GB/T12234 ASMEB16.34
   結構長度 JB/T3595
   接口連接尺寸 JB/T3595 GB/T12224
   檢驗與試驗 JB/T3595 MSS SP61
   壓力與溫度基準 JB/T3595 ANSI B16.34
GB、JB鍛鋼法蘭閘閥主要壓力等級
   公稱壓力 200、250、320
   工作壓力P55100V、P55140V、P55170V
GB、JB鍛鋼法蘭閘閥結構優勢
   1.采用壓力自緊式密封,閥體支管兩端為焊接連接。
   2.閥坐、閥瓣密封面采用鈷基硬質合金等離子噴焊而成,耐磨、抗擦傷性能好。
   3.閥桿經抗腐蝕性氮化處理,有良好的抗腐蝕性和抗擦傷性。
