3. General lathe processing
4. The machine punch the product parts
5. Cold Forming Molding
6. Welding Assembly
Valves is famous for manufacturing fully welded ball valves in China market, we have made 56”CL600 fully welded ball valves for Iran market, a special technique was performed so that post welding heat treatment is not required so soft seals will not to be damaged during the welding process to make sure the seals good performance.

| Other remarks 1 | The valve seat is embedded with flexible seal ring for zero leakage of seal; the valve seat is provided with a preloaded spring that is adaptive to the variation of pressure and temperature, so leakage is not liable to happen. |
| Other remarks 2 | Integral valve with welded valve body, free of external leakage, etc. |
| Other remarks 3 | Fire resisting construction of all-welded ball valve. Each leakage position is designed with flexible graphite packing or stainless steel mixing graphite to satisfy the fire resisting requirements in case of a fire. |
| Other remarks 4 | The most advanced support plate structure both at home and abroad is adopted for large diameters to increase the service life and reduce the operating torque of valve. Thus, the service life of valves is greatly extended. |
| Other remarks 5 | The directly-buried all-welded ball valve can be buried directly, in which case, no high and large valve pit is required, only a small shallow pit needs to be built on ground, so the construction cost and the engineering time can be significantly saved. |
| Other remarks 6 | Full bore of valve convenient for pigging, of small flow resistance and high flow capacity and good flow characteristics |
| Other remarks 7 | The valve ball can completely enclose the valve seat when the all-welded ball valve is opened, so the impurities in the medium will not be flushed to the valve seat or the packing surface of valve body. Hence, the valve body has a same service life as the pipeline due to his special construction. |
