Automatic Flow Balancing Valve

Automatic Flow Balancing Valve

The automatic flow balancing valve can automatically adjust the valve opening through the built-in pressure compensation mechanism regardless of how the pressure in the system fluctuates, ensuring that the flow of each branch remains within the set range. It is widely used in heating, air conditioning, cooling water circulation and other systems.

 

Product Features

Automatic flow control: No external power supply is required. Relying on the built-in flow regulating device, the flow is automatically adjusted according to the system pressure changes to ensure that the flow in the pipeline remains constant.

 

Precise balance: Through the pressure compensation mechanism, the flow is precisely controlled to eliminate the uneven flow caused by pressure fluctuations and ensure the flow of each branch in the system is consistent.

 

Debug-free design: No additional debugging is required after installation, and it automatically adjusts to the set flow, which greatly simplifies the debugging and maintenance of the system.

 

 Automatic Flow Balancing Valve
  • P/T measuring ports are 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. (PICV)

  • 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.

FAQ

 

1.How will the automatic flow balancing valve react after the water supply is cut off?

The valve will automatically shut off the flow, maintain a safe state, nd continue to maintain the set flow after the system resumes water supply.

 

2.Can the auto balancing valve be used in combination with a variable frequency water pump?
Yes, the auto flow balancing valve combined with the variable frequency water pump can further optimize the system efficiency and adjust the pressure through the water pump to adapt to actual needs.

 

3.How to choose the right material for the automatic flow balancing valve?
Depending on the type and temperature of the medium, choose stainless steel, brass or other corrosion-resistant and high-temperature resistant materials to ensure that the valve can operate reliably in special environments for a long time.

 

4.Does the auto balancing valve have a shockproof design?
Some models have a shockproof design and can operate stably in a slight vibration environment, especially suitable for industrial cooling or water pump systems.

 

5.How fast does the automatic balancing valve react?
The automatic balancing valve can usually respond to pressure changes and adjust the flow in a short time. The specific reaction speed depends on the valve design and working conditions, but it is generally adjusted within a few seconds.
