Maximize energy savings while addressing unique control challenges like unstable room temperatures with a Pressure Independent Control Valve (PICV) from Honeywell. Each PICV is an automatic temperature control valve, an automatic flow – regulating valve and a flow-limiting valve packaged into one body. The PICV regulates and maintains a constant flow to the coil, irrespective of differential pressure variations, and is used in heating and cooling systems for both air handling units and fan coil units.
