<p>This Architectural Drawing is of (PIBCV) Without Pressure. Pressure Independent Control Valves or Pressure Independent Balancing and Control Valves – <strong>also commonly known as PICVs (or PIBCVs)</strong> – are getting more and more popular in both 2- and 4-pipe heating and cooling applications due to their accurate flow control at any load condition. <strong>The diaphragm reacts to the system and regulates the pressure differential across the actuated control valve orifice to maintain its flow rate</strong>. On a PICV (see graphic below), when pre-setting the maximum flow rate, the inlet orifice changes in size, which does not interfere with the length of the stroke.
