(ASME ANSI API )美標閘閥
簡要描述：RETZ進口ASME、ANSI、API美標鋼制閘閥啟閉件閘板，閘板的運動方向與流體方向相垂直，閘閥只能作全開和全關，不能作調節和節流。閘閥通過閥座和閘板接觸進行密封，通常密封面會堆焊金屬材料以增加耐磨性，如堆焊1Cr13、STL6、不銹鋼等

(ASME、ANSI、API )進口美標鋼制閘閥將手輪向左旋轉時，閥板會向上移動，此時流路開，反之將手輪向右移動時，閥板會向下移動，此時流路逐漸被關閉。
retz品牌 (ASME, ANSI, API) When the handwheel of American standard steel gate valve is rotated to the left, the valve plate will move upward, and the flow path will be opened at this time; otherwise, when the handwheel is moved to the right, the valve plate will move downward, and the flow path will be gradually closed
