Gate valve defects gate valve installation and maintenance

The shortcomings of the valve ① processing than the closing valve complex; ② seal surface is not easy to repair after wear and tear; ● Dimensions high; open and close a long time. Gate valve installation and maintenance ① double gate valve should be installed upright, that is, the stem in a vertical position, hand wheel at the top. Manual single gate valve can be installed anywhere. ② with the valve drive mechanism (such as gear transmission, electric, pneumatic or hydraulic, etc.) should be installed according to the provisions of the product manual. ③ hand wheel, transmission are not allowed to lift, and no collision. ④ With bypass valve gate valve to balance the import and export of pressure and reduce the opening force, so before opening, you should open the bypass valve.
