Dynamic Flow Balancing Valves(W-DP71-25Q)

Type:Dynamic Flow Balancing Valves(W-DP71-25Q)

Class:HVAC Products



The Series W-DP71 dynamic flow balancing valve is designed

for air-conditioning or heating system to keep the flow less

than or equal to design value. It is generally used in constant

flow systems.


- Dynamic Balancing: constant flow is achieved through the

valve plug’s auto-adjustment of the opening rate when ΔP

fluctuates in the system

- Precision calibrated valve plug keeps the flow deviation no

greater than ±5%

- The flow rate is factory preset multiple ΔP ranges available

for each size

- No on-site commissioning is needed, saving time and labor


- No need of re-balancing after system changes
