DN50-300 Ductile Iron Self Operated Dynamic Flow Balance Valve with 1.6MPa Rating for HVAC Systems
Automatically regulates and balances fluid flow in pipeline systems by responding to pressure changes, ensuring stable flow across all branches without external power requirements.
Self operated dynamic flow balance valves automatically adjust valve opening based on system pressure changes to achieve dynamic flow balance. These valves are essential for building HVAC systems, water supply systems, and other applications requiring precise dynamic flow control.
The valve combines an automatic regulating mechanism with manual adjustment capabilities, utilizing medium pressure as the driving force to maintain branch pipeline flow balance. Features include flow stabilization, opening indication, locking capability, and shut-off function. Suitable for non-corrosive media in heating and air conditioning applications.
