Hydraulic bleeder manifold possesses two functions: hydraulic bleeder and manifold. In heating system, if there is only one heat source system and multiple secondary circulating systems, it can adapt to different heating functions in different areas. In the system, the primary circulation and secondary circulation run independently, without influencing each other. When pumps of secondary circulating system are completely or partially switched off, the flow capacity opened by the primary circulating system will completely or partially return to the primary system through the bypass inside the hydraulic bleeder, so as to efficiently balance and protect independent heating equipment systems and safety.
