Product description
The self-operated flow balance valve is mainly composed of an automatic valve flap and a manual valve flap. Using the automatic pressure change of the medium as the power, the balance of the flow of each branch pipeline is automatically adjusted, and the flow is accurately stabilized. At the same time, it has the kinetic energy of opening indication, locking, closing and so on. It is suitable for flow control of non-corrosive media such as heating and air conditioning. One-time adjustment before running can make the system flow automatically constant at the required set value.
