Hydraulic Balancing Valve

Why use a balance valve(41-05)

Hydraulic balance is necessary to avoid the following problems :

Some rooms almost never achieve the desired room temperature or are not cooled sufficiently. This problem especially arises in case of influence of other heat sources.

After changing over from low temperature to heating operation, it takes time to heat the parts in the system.

Indoor temperature changes, especially in the case of small demand, there is a greater possibility of this situation.

Consume more energy

It is unusual if the above problem happens.

41-05 Hydraulic Balancing Valve

Distribution of flow

If the drag in some parts of the piping is unbalanced, it will lead to unbalanced distribution of flow. The disposal to this problem is to install a Balance Valve in the piping and use a specific adjusted instrument to balance the drag in the system.

The illustration shows that the pump has to produce a differential pressure at least ΔPtotal to guarantee a sufficient supply to appliance 4. This will, however, inevitably result in an excessive differential pressure at the appliances 1 to 3. Such high a differential pressure will cause overheat or under heat and a waste of energy.

The principle of Balance Valve

The principle of balance is to adjust the gap between the core and the seat, for fluid flow through the valve, the gap changes the valve’s resistance, and the flow rate will be adjusted. The balance valve equals to a local part, which resistance can be adjusted. For fluid can not be compressed, there is the flow rate formula.

Q	：Flow rate of fluid through the balance valve（m³/h）
Kv	：The balance valve’s resistance modulus, which can be adjusted
ΔP	：Different pressure before and behind the balance valve（bar）

Kv is a modulus of a balance valve. It means, if the differential pressure before and behind a balance valve is 1 bar（1.02 kg/cm2）, the flow rate through the balance valve is Kv（m3/h）. And the valve’s Kv will no changes if the open rate of the valve’s core is not changed. That is, the opening rate of a balance valve determines the valve’s Kv.

The balance valve can be used in following conditions

The balance of boiler or ice water engine group

The balance of section’s cooling or heating system

The balance between ice water engine group and cooling tower

The balance of heating (or cooling) net in buildings

Hydraulic Balancing Valve Adjustment

DN20~DN500, there are four types of wheels, similar in structure and function, and all have two scales.

0~10 graduated horizontal line: represents 1 turn.

0~9 tens of numbers: represents 0.1 turn.

Installation Position

The Hydraulic Balancing valve should be possibly installed at the section of the straight pipe to stabilize the flow through the valve and to ensure the accurate measurement since the Valve has the function of measuring the rate of flow. Avoid installing the valve at the side of water supply, pump outlet and the position of turbulent flow.

Recommendation：

The distance between the curved pipe and the branch pipe is at least over 5D and 2D.

The distance between the pump outlet and the branch pipe is at least over 10D and 2D.

※D is the caliber of the Balancing Valve
