The double gate valve should be installed vertically (i.e. the stem is in the vertical position and the hand wheel is at the top). 3、带有旁通阀的闸阀在开启前应先打开旁通阀(以平衡进出口的压差及减小开启力 )。 3. The gate valve with bypass valve should be opened before opening (to balance the pressure difference between inlet and outlet and reduce the opening force). 4、带传动机构的闸阀,按产品使用说明书的规定安装。 4. The gate valve with transmission mechanism shall be installed according to the provisions of the product operation manual. 5、如果阀门经常开关使用 , 每月至少润滑一次。 5.
