Siemens PICVs are selected on flow

The only information needed to the size of Siemens Acvatix PICV (pressure-independent control valve) is the required flow through it, saving time for the specifier. These valves automatically shield against pressure fluctuations in a network to maintain a constant flow. The are available in sizes from 15 to 150 mm (a 50 mm size is pictured).

These valves enable a building to be commissioned in sections and for late changes in the design to be more easily incorporated. It is also possible to shut down sections of an HVAC system, a feature that suits these valves to refurbishment projects.

Because the control of Acvatix valves is independent of differential pressure, they ensure more accurate temperature control. The return temperatures remain at the correct level under all operating conditions, ensuring high efficiency in the generation of heating and cooling energy.
