1. The installation position, height, and inlet/outlet direction must meet the design requirements, and the direction of medium flow should be consistent with the arrow direction marked on the valve body. The connection should be firm and tight.
2. Before installing the valve, a visual inspection must be conducted, and the valve nameplate should comply with the current national standard "General Valve Marking" GB 12220. For valves with a working pressure greater than 1.0 MPa and a shut-off function on the main pipeline, strength and tightness tests should be conducted before installation, and they can only be used after passing the tests. During the strength test, the test pressure shall be 1.5 times the nominal pressure, and the duration shall not be less than 5 minutes. The valve shell and packing shall be qualified if there is no leakage. During the tightness test, the test pressure is 1.1 times the nominal pressure; The duration of the experiment meets the requirements of GB 50243.
