B3 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, reliability and long life.
