Cemented-carbide valve core:  As an important component of valve body parts, the valve core requires high precision, high heat resistance, high wear resistance, with advanced manufacturing technology necessary high productivity and high quality requirements, the valve core made of common materials can not meet the requirements of high and new technology, and the cemented carbide valve core made of WC-Co powder alloy material by special technology has high precision, corrosion resistance, wear resistance, high temperature resistance and small deformation, quality and efficiency than ordinary metal material spool increased dozens of times, even hundreds of times, which is favored by the market, widely used in various industries. Wuxi Kairun cemented-carbide products factory can produce in a variety of specifications and shapes of cemented-carbide valve core.
