Festures of Dynamic Balancing Valve

No external energy is required for automatic flow regulation;

utomatically 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 valve tank 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.
Dynamic Balancing Valve Installation 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.
