Per Product Specification:

The Series PICV (Pressure Independent Control Valve) consists of two functional controlling segments.  The first segment is a pressure-balanced control valve, actuated by a high-thrust electric motor actuator.  The electric actuator provides precise positioning of the valve closure mechanism, and responds quickly and precisely to the electronic control signals supplied to them.  The second segment is a differential pressure control valve that operates independently of the control segment.  This segment is self-powered (self operating) and does not burden or interact with the building automation control system.  By quickly raising or lowering its own resistance to flow, the differential pressure control segment of the PICV regulates and stabilizes the pressure drop across the control valve segment by absorbing unused head pressure.  This compensates for changes in pumping pressure resulting from pump switching or from varying flow demands in its’ own, or parallel flow paths and results in pressure independent operation.
