Balance Valve

The main function of a balance valve is to achieve flow balance by adjusting the relative balance of pressure on both sides of the pipeline before and after the valve or by diverting flow, in order to alleviate the pressure difference inside the pipeline, ensure that the pressure inside the pipeline is always in a relatively balanced state, and avoid pipeline rupture. Its working principle is to adjust the flow rate by changing the clearance (i.e. opening) between the valve core and the valve seat, thereby changing the flow resistance of the fluid passing through the valve. The balance valve plays a role in dynamic and static balance regulation under hydraulic conditions. It adjusts the flow rate by changing the clearance between the valve core and valve seat to alter the flow resistance of the fluid through the valve. This adjustment can be static or dynamic, depending on the design and application scenario of the valve. The static balance valve consumes excess pressure difference by manually adjusting the valve opening, eliminating hydraulic imbalance between various circuits. The dynamic balance valve automatically adjusts the resistance coefficient according to changes in system operating conditions to maintain a constant flow rate. It can effectively solve the problem of uneven flow distribution in the pipeline network, ensuring that each branch increases or decreases flow proportionally and maintaining the hydraulic balance of the system. In addition, the balance valve also has a special function of digital locking, which can lock the opening after one-time debugging through a dedicated intelligent instrument to ensure the stable operation of the system. The balance valve produced by Shanghai Meiyan Yipump Valve is widely used in various HVAC pipelines, effectively balancing pipeline pressure and playing an energy-saving and emission reducing role in central air conditioning.
