The model selection is as follows: 1. Use existing data, such as product catalog and product samples, to select appropriate eccentric hemisphere valves； 2. Determine the nominal diameter and connection mode of the connecting pipe of the eccentric hemisphere valve, such as flange, thread, welding, etc; 3. Determine the operation mode of eccentric hemisphere valve, such as manual, electric, electromagnetic, pneumatic, hydraulic, electrical linkage and electro-hydraulic linkage; 4. Determine the parameters of the eccentric hemisphere valve, such as structural length, connection mode, flow resistance, discharge capacity, size and number of connecting bolt holes, and then determine the nominal diameter of the pipe and the diameter of the valve seat hole; 5. The material of the selected eccentric hemisphere valve shall be determined according to the medium conveyed by the pipeline, working pressure and temperature, such as gray iron, malleable iron, ductile iron, carbon steel, alloy steel, stainless acid resistant steel, copper alloy, etc。
