1. Tips for choosing dynamic balancing

2. Dynamic balancing valve has an internal membrane capable of automatically adapting to the present conditions - similar to the operation of the expansion tank, which manages system changes by working on the membrane that expands or does not. Dynamic balancing valves are provided above all where there are terminals such as fan coils, ceiling boxes, or utilities that would be affected by yield variations in flow rate. Often they are also used as zone valves. Static balance Static balancing valves define a valve duty point, the maximum flow rate that the valve must maintain when the system is running, based on a defined differential pressure value at the valve. 

3. When should hydraulic balancing be carried out? The ideal would be to do this in all users, large and small, even if the problems that may arise from the lack of balance are usually accused more by condominiums than single-family users. In recent years, the biggest problems that have been encountered have been linked to redevelopment, with the obligation to install thermostatic heads in large condominiums. With thermostatic valves, less flow to smaller radiators. The radiator valve with pre-regulation was created to carry out these balancing operations on the heating body more specifically.

4. How balancing works • The balancing valves are divided into flow balancing valves; differential pressure control valves. In turn, balancing the flow rates can occur in a "static" or "dynamic" way. The pre-regulation is set on the valve, according to the parameters defined upstream by the thermomechanical designer, who establishes the necessary flow rates based on the users, always with a view to energy saving. • After making the mapping, the designer defines the preset value, determining the flow rate inside the single radiator. If this mapping is available, the installer only has to follow and set this value, which is set directly on the valve. However, these are very simple devices, even in the absence of mapping.

5. From the leaf to the trunk From the level of the radiator - which is the terminal part of the system, like the leaf for the tree - the same concept can be transferred to the whole system: the radiators are balanced at the level of the single apartment, but if you move one level and if you consider the entire condominium it is clear that if a system is balanced in apartment A, it must be expected that it is balanced also in apartment B - vice versa, the problems of "unbalancing" affect the latter. At this point, even the distribution branches that go to the individual users need balancing. If there are two apartments with radiators already balanced in the case of a small condominium or a one-two-family house, the riser will also be balanced. 

6. It is useful to balance risers not only to optimize the system but also because balancing valves can perform additional functions, usually entrusted to additional components on the system. It allows intercepting the branch or column, without the need to install the classic shut-off ball valve upstream or downstream. • In addition, equipped with a loading and unloading cock, in case of maintenance, it allows to intercept the single branch, unload that part of the system and, once the work has been carried out, return to load the system, without intervening on the remaining part of the system.

7. How to set the preset value • An adjustment scale characterizes the balancing valves. Usually, it is the designer who, upstream, evaluates the balancing on the single branches and the single risers and gives the installer the presetting value that he has to set on the handwheel. The valves have a handwheel with a number gradation.Many of these valves also have the possibility of being blocked and sealed. In this case you should contact Dynamic Balancing Denver.
