Pressure Independent Control Valve

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.

  • High close-off pressure
  • Better flow control, full stroke modulation at all times
  • Compatible to multiple actuators
  • Electronic failsafe actuators available for all sizes (super cap.)
  • Easy installation
Benefits
  • COST AND
    ENERGY-EFFICIENT

    • Enhances energy savings due to optimal control, lower flow, and pump pressure
    • Speeds up response time and increases system stability
    • Maintains system balance perfectly, under all conditions, increasing energy efficiency
  • ACCURATE
    FLOW CONTROL

    • Ensures the correct water flow for each unit automatically
    • Regulates flow with precision and empowers optimum sizing of chillers, boilers, and pumps
    • Automatic balancing eliminates overflows, regardless of fluctuating pressure conditions in the system
  • EASY TO
    INSTALL AND USE

    • Simple, field-adjustable settings that accommodate any design flow in the flow range
    • ‘Sealed’ setting means the actuator covers the setting and protects against tampering
    • Two-way, modulating solution that accepts either digital or analog input signals
    • Internal parts can be accessed without removing the valve housing from the piping lines
  • FLEXIBLE
    PERFORMANCE

    • Compact, one-unit solution that includes the modulating control valve, the dynamic flow limiter, and the differential pressure control valve
    • Full range of sizes from 15 mm (1/2”) to 250 mm (10”)
    • High flow with minimal required differential pressure
    • Available electrical actuators with selectable control modes, ‘Linear’ or ‘Equal’ percentage
    • No balancing is required when further stages are added to the system, or if the dimensioned capacity is changed
