Top entry ball valve is particularly applicable for such industries as petroleum, chemical engineering and nuclear power plants. Its body adopts an integrated design, thus reducing leak points. Its seat design is available for either soft or hard seal, easy for maintenance. With its advanced manufacturing process and reasonable structure design, it can bear high temperature and high pressure, so it has a wide application scope.

QYI integrated forged valve adopts a one-piece body structure without leakage points in the middle. With its advanced forging process, its packing design is more reasonable, thus ensuring its zero leakage. This valve series is especially applicable for harsh working conditions, like high temperature, high pressure and severe erosion, in the power industry. Its unique structural design and hardening treatment technology of sealing surface ensure its safety,
