Schematic diagram of the product shape and structure size
1, hand wheels, handles and drive mechanism for lifting are not allowed to use, and non-collision.
2, Gate Valve should be installed vertically (ie, stem in a vertical position, the hand wheel at the top).
3, the valve with a bypass valve opens the bypass valve in the open should be preceded by (in order to balance the import and export of pressure and reduce opening force).
4, with the valve drive mechanism, according to the provisions of the product installation instructions.
5, if the valve often used switches, lubrication at least once a month
