TIEMME PRESSURE INDEPENDENT CONTROL VALVES (PICV)


TIEMME PRESSURE INDEPENDENT CONTROL VALVES (PICV)

THE SOLUTION FOR A PROPER BALANCING OF THERMAL SYSTEMS

The correct functioning of a heating system is strictly linked to the balancing of the distribution network. The design flow rate must be available at all delivery terminals, even the ones furthest away from the heat transfer fluid circulation pumps.
The energy efficiency of a system begins with the correct calculation of the thermal loads, in turn linked to the flow rate and the temperature of the fluid necessary to satisfy the energy demand of the terminal.
The correct distribution of the flow rate through the so-called balancing organs is essential, and allows to avoid non-homogeneous distributions of heat/cold and noise phenomena of the hydraulic components.

One of the most efficient solutions on the market is the inclusion of pressure independent flow control valves (PICV) in the system.
Thanks to a diaphragm device with a contrast spring, the PICVs keep the flow rate constant within a certain differential pressure range. The devices consist of a brass valve body combined with a regulation cartridge selected according to the type of operation and the required working conditions (flow rate, differential pressure).
