Super core valve is a collection of development, design, processing and manufacturing of hard sealed ball valves, high temperature ball valves, high pressure ball valves, small diameter ball valves, low temperature ball valves, thermal ball valves, wear-resistant ball valves, soft sealed ball valves, and other products. The company has many years of research and production of hard sealed ball valve practical experience, all parts of the product are standardized production, to bring greater convenience to product installation and maintenance. Among them, our company's ball grinding of STL spherical surface has reached the domestic advanced level, and the overall round start of the sphere can reach 0.005-0.01mm, and the surface roughness can reach 0.8-0.2μm. It has been used by many large domestic valve manufacturers and has been quite well evaluated and trusted. The hard sealed ball valve produced by our company, whether it is type 41 or type 47, can reach zero leakage during gas and water pressure test. At the same time, our company has developed a new QZ type track prop-open hard seal ball valve this year, the hard seal ball valve has: high pressure resistance, high temperature resistance, no friction, two-way seal, low torque, full diameter, low noise and other characteristics are the ideal replacement products for gate valves. The company spirit of "only professional, can be reliable" quality belief for the major customers to provide more quality products.
