Zhejiang Jigong Valve Co., Ltd. is one of the most reliable manufacturers and suppliers of solid valve ball in China. If you're going to wholesale cheap solid 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 solid valve ball is made from an integral solid billet through forging or precision machining, featuring a dense structure and extremely high strength. It can effectively withstand high pressure differentials, high-frequency operations, and erosion and deformation caused by particle-containing media, with excellent sealing surface stability and long-lasting zero-leakage performance. Its high-strength characteristics make it suitable for on-off and regulating control of high-pressure, high-temperature, and highly corrosive media, and it is an ideal valve ball component for extreme working conditions such as oil and gas extraction, refining units, coal chemical industry, and high-pressure steam pipelines.
