New Breakthroughs in the Application Fields of New Ceramic Valves

At present, the valves commonly used in production across various industries in China are metal valves. Metal valves have a history of over a hundred years. Although structural and material improvements have been made during this period, limited by the inherent conditions of metal materials, they are increasingly unable to meet the requirements of harsh working conditions such as heavy wear and strong corrosion. This is mainly reflected in short service life and serious leakage, which greatly affect the stability of system operation. Traditional metal valves urgently need thorough innovation in materials, design and manufacturing processes.

As a new material of the 21st century, advanced ceramic materials have attracted increasing attention from scientific researchers. Applying them to industrial valves is a bold and beneficial innovation.

According to relevant experts, new ceramic valves have four major advantages. First, high-tech new ceramic structural materials are used to manufacture valve sealing parts and wearing parts, improving wear resistance, corrosion resistance and sealing performance of valve products and greatly extending valve service life. Second, the use of ceramic valves can greatly reduce valve repair and replacement frequency, improve the safety and stability of supporting equipment operating systems, reduce workers' labor intensity and save equipment repair costs. Third, the use of ceramic valves can improve the sealing performance of industrial piping systems while eliminating leakage to the greatest extent, playing a positive role in promoting environmental protection. Fourth, ceramic raw materials are widely available and low in cost. High-performance ceramic materials can be produced from common elements such as aluminum, carbon and silicon, saving large amounts of metal materials and scarce mineral resources.

New ceramic valves are mainly applied in power generation, petroleum, chemical, metallurgy, mining, wastewater treatment and other industrial fields. Especially under harsh working conditions involving heavy wear, strong corrosion, high temperature and high pressure, they demonstrate outstanding performance. They can satisfy high-wear and strong-corrosion service environments, and their most prominent feature is ultra-long service life, with performance-to-price ratio far superior to comparable metal valves. With the continuous development and progress of science and technology, ceramic technologies in material formulation, forming, machining and assembly processes have become increasingly mature and complete. With their excellent performance, ceramic valves have gained growing recognition from industry professionals.
