The core advantage of high-pressure forged gate valves lies in their high-strength valve body structure. Compared with traditional cast valves, the forging process significantly improves the density and uniformity of the valve body, eliminating internal defects and enabling the valve body to withstand higher pressure and impact. Forged gate valves usually use high-quality carbon steel or alloy steel as the base material. After forging at high temperature and pressure, these materials have higher tensile strength and yield strength, and can maintain structural stability under extreme working conditions.
II. Durability Advantages of High-pressure Forged Gate Valves
The durability of high-pressure forged gate valves is reflected not only in their high-strength valve body structure but also in their precise sealing design and corrosion-resistant performance. The following are the main features of its durability:
High-pressure forged gate valves adopt multi-stage cemented carbide sealing surfaces, combined with a fine grinding process. This ensures that the sealing rings fit tightly to the valve seats under high-temperature and high-pressure conditions, achieving zero leakage. In addition, its sealing design also has a pressure self-tightening function. As the system pressure increases, the sealing effect becomes even better, further improving the reliability of the valve.
The valve bodies and internal parts of forged gate valves are usually made of corrosion-resistant materials, such as stainless steel and nickel-based alloys. These materials can effectively resist the corrosion of the medium and extend the service life of the valve. Moreover, through surface treatment technologies, such as plating and coating, the
corrosion-resistant performance of the valve is further enhanced.
