Zhejiang Jigong Valve Co., Ltd. is one of the most reliable manufacturers and suppliers of tungsten carbide (tcc) valve ball in China. If you're going to wholesale cheap tungsten carbide (tcc) valve ball made in China, welcome to get pricelist from our factory. All customized products are with high quality and low price.
Basic Introduction
The tungsten carbide valve ball is coated with a tungsten carbide (WC) hard layer on the substrate surface through supersonic spraying or surfacing welding processes, with a surface hardness reaching HRC 65–75. It has excellent wear and erosion resistance, can withstand high-speed erosion and strong corrosion from media containing solid particles, is suitable for harsh working conditions of high pressure, abrasion, and strong corrosion, and is the core sealing component of high-end valves for harsh working conditions.
