Features
-
P/T measuring port is available.
-
The valve characteristics are not affected by the flow setting size.
-
It is composed of an adjustable flow dynamic balancing valve, a dynamic pressure difference balancing valve and a regulating valve with full stroke adjustment capability, integrating three valves in one.
-
It can achieve 100% adjustment and balance of water volume in the system, while creating a more comfortable environment and energy-saving effect. When the system is rebuilt again, it does not need to be hydraulically balanced again.
