Disadvantages of gate valve

    ① Processing is more complicated than globe valve;

    ② sealing surface wear is not easy to repair;

    ③ high external dimensions; long opening and closing time.

Gate valve installation and maintenance

    ①Double gate gate valve should be installed upright, that is, the valve stem is in a vertical position, the handwheel at the top. Manual single-gate gate valve can be installed in any position.

    ② gate valve with transmission mechanism (such as gear drive, electric, pneumatic or hydraulic, etc.), should be installed in accordance with the provisions of the product instruction manual.

    ③ The handwheel and transmission mechanism are not allowed to be used for lifting, and collision is strictly prohibited.

    ④ The gate valve with bypass valve can balance the pressure difference between the inlet and outlet and reduce the opening force, thus the bypass valve should be opened before opening.
