- Storage and maintenance
Valves can be stored in any area of the mask, but must pay attention to prevent the valve is soil or ground dirty. At the time of shipment, the inlet and outlet of the valve are provided with a protective cover. Note that before the installation of the valve, do not remove these protective cover. When the valve is ready to be installed, the protective end cover is removed first, and then the connection parts are cleaned. If is the butt welding end of the valve, to remove all visible foreign body. Use suitable solution to clean the parts that need to be welded, such as acetone or alcohol. Do not use a solution containing fluoride or chloride.
Installation and maintenance
1 handwheel, handle and drive mechanism for lifting are not allowed to use, and avoid collision.
2 double gate valve should be installed vertically (that is, the valve stem is in the vertical position, the hand wheel at the top).
3 valve with bypass valve should be opened before opening the bypass valve (in order to balance the pressure of the inlet and outlet and reduce the opening force).
4 with the transmission mechanism of the gate valve, according to the provisions of the product manual installation.
5 if the valve is often used to switch, at least once a month.
