The all-welded ball valve with double piston floating seat and single seat four-fold sealing structure produced by our company has the following advantages: 1. Safe and reliable sealing performance: double piston floating seat, four-fold sealing structure to ensure that the valve under high pressure, high temperature and corrosive media to achieve bidirectional zero leakage, improve the safety, stability and reliability of the system. 2. Strong adaptability: Double piston floating seat design has strong adaptability to changes in pressure and temperature, suitable for a variety of working conditions. 3. Long life: high-precision processing and high-quality material selection make the valve wear-resistant and corrosion-resistant, extending the service life. 4. Low maintenance cost: reasonable structure design, easy installation and maintenance, reducing the cost of use. In summary, the welding ball valve with its excellent sealing performance, wide adaptability, long service life and simple maintenance, in the field of heat, petroleum, chemical, natural gas and other pipeline transportation has significant advantages.

All-welded ball valve body is manufactured by welding after the whole forging, and its advantages mainly include: 1. Improve the bending moment and stretching ability of the valve body: the overall forging process of the valve body improves the bending moment and stretching ability of the valve body, so that it can withstand higher working pressure and temperature. 2. Improve high sealing: The valve body adopts submerged arc welding process to ensure the quality of the weld and reduce welding defects, thus improving the sealing performance of the valve and preventing media leakage. 3. Extend the service life: The combination of the overall forging and submerged arc welding process of the valve body makes the valve body have higher corrosion resistance and wear resistance, and extends the service life of the valve. 4. Reduce maintenance costs: Due to the compact structure and good sealing of the valve body, the maintenance needs caused by leakage and other problems are reduced, and the maintenance costs are reduced. In summary, the welded ball valve body adopts integral forging and advanced submerged arc welding process, which can significantly improve the performance and service life of the valve and reduce maintenance costs.
