The silicon nitride valve core has the characteristics of erosion resistance, corrosion resistance, and thermal shock resistance. At the same time, it has self-lubricating properties. The friction coefficient during valve switching is low. The coupling between the valve core and the valve seat is tighter, and the sealing performance is better. The service life is dozens of times of the general steel ball valve. At present, Xinjiang Jingshuo New Materials Co., Ltd. can produce the maximum diameter of the valve core up to 150mm according to customer requirements, and the valve diameter can achieve full coverage of 15-100mm.
Ball valves, disc valves, and regulating valves made with silicon nitride as the valve core can be widely used in many industries such as photovoltaic, coal chemical industry, electric power, metallurgy, petroleum, petrochemical, etc.
