Advantages of Zigong Xingyu
Zigong Xingyu is the expert in making all kinds of tungsten carbide throttle valve seats and balls based on your drawings and requirements, and has the deep understanding market demanding. We own a lot of core patent technologies about valve seats and balls in the sealing, pumps, oil, and other fields. At the same time, we have the self-develop team and cooperate with many institutions in quality check and material research. And we’ve built the long-term cooperation with many famous companies, such as Alcoa and Harding. Besides, our products can help us to improve the work efficiency and reduce the cost.
Application of Tungsten Carbide Valve Seats
Compared to traditional steel valve seats and balls, the corrosion-resistance of tungsten carbide is 5-10 times higher, which can greatly prolong the service life and enhance the work efficiency. Due to tungsten carbide can withstand the acid and corrosion medium, like H₂S, CO₂, Cl⁻, etc. This makes the tungsten carbide valve seats and balls perform well in the severe conditions, for example, oil&gas, chemical industries. Tungsten carbide can keep stable under the high temperature, and is more reliable in high pressure, preventing thermal deformation and leakage. Tungsten carbide has the excellent impact-resistance, usually the content of cobalt 10%~20% can improve the resilience of valve seats and balls.
