PICV in fan coils: what is a pressure independent control valve and why is it used

The PICV combines flow regulation functionality with independence from network differential pressure variations.

Constant design flow

The valve limits the fan coil flow rate to the preset value even when the differential pressure in the network changes.

Better balancing

It helps ensure that nearby fan coils do not "steal" water from more distant ones.

Variable flow

It is particularly suitable for installations with two-way valves and variable speed pumps.

Correct selection

The PICV must be selected based on the required flow rate, the available differential pressure, and the manufacturer's technical specifications.
