Dynamic Balancing Valve
Festures of Dynamic Balancing Valve
No external energy is required for automatic flow regulation;
Automatically adjust equipment or pipeline flow to meet the required design flow;
No need for balance debugging before the system runs;
Keep pipe flow constant.
Dynamic Balancing Valve Working Principle
When the pressure difference control range is above, the butterfly valvetank is completely compressed, and the cross flow area is only the minimum design channel, and the flow rate changes with the pressure difference. When the pressure difference is within the control range, the valve tank moves with the pressure difference, thus changing the flow area and keeping the flow at the set value. Under the pressure differential control range, the valve is fully extended to reveal the maximum over current area, and the flow rate changes with the pressure difference.
Flow Design Balancing ValvesInstallation and Commissioning
This valve is mainly used for flow regulation and hydraulic balance. It can not be used as a shutoff valve because there is a certain amount of leakage when it is closed. For specific use, please consult Zeco Valve Group.
