Working Principle:

A static balancing valve is essentially a throttling element with precisely adjustable and lockable resistance. Its working principle mainly involves the following three steps:

1. Resistance Adjustment for Flow: By manually rotating the valve handle, the gap between the valve core and the valve seat (i.e., the valve opening) is changed. The change in opening directly alters the local resistance of the fluid flowing through the valve, thus precisely controlling the flow rate through that pipe section.
2. Dedicated Instrument-Assisted Commissioning: The valve is typically equipped with a pressure-measuring valve (test interface). During system commissioning, technicians use dedicated intelligent instruments connected to these interfaces to measure the pressure difference before and after the valve, and, combined with the valve opening, directly calculate the current actual flow rate.
3. Locking the Opening to Maintain Balance: Once the flow rate is adjusted to the design requirement, the valve opening is fixed by a digital locking device. As long as the total system flow rate does not change drastically, the flow ratio of each branch pipe will remain constant, thus eliminating the hydraulic imbalance phenomenon of "higher flow at the near end and lower flow at the far end" in the system.
