PICV Pressure Independent Control Valves | VSXT-04PB 3/4inch PICV Valve, Stroke 5mm, for MV30 Actuators

VSX..PB/VSXT..PB PICV pressure independent balancing & control valves can be used in heating and cooling systems in applications with Fan Coil Units, Chilled Beams or other terminal units applications. VSX..PB/VSXT..PB PICV valves provide modulating control with full authority regardless of any fluctuations in the differential pressure of the system.

VSX..PB/VSXT..PB PICV valves (Pressure Independent Control Valves) combine an externally adjustable automatic balancing valve, a differential pressure control valve and a full authority modulating control valve.

VSX..PB/VSXT..PB PICV valves make it simple to achieve 100% control of the water flow in the building, while creating high comfort and energy savings at the same time. An additional benefit of PICV valves is that no balancing is required if further stages are added to the system, or if the dimensioned capacity is changed. Energy saving is due to optimal control, lower flow and pump pressure. Maximized dT is due to faster response and increased system stability.

Design Benefits of PICVs (Pressure Independent Control Valves):-

  • Less time to define the necessary equipment for a hydraulic balanced system (only flow data are required).
  • No need to calculate valve authority. Always one.
  • Flexibility if the system is modified after the initial installation.

Installation Benefits of PICVs (Pressure Independent Control Valves):-

  • No further regulating valves required in the distribution pipework when VSX..PB/VSXT..PB is installed at terminals.
  • Total number of valves minimized due to the 3-in-1 design.
  • Minimized commissioning time due to automatic balancing of the system.
  • No minimum straight pipe lengths required before or after the valve.

Operation of PICVs (Pressure Independent Control Valves):-

  • High comfort for the end-users due to high precision temperature control.
  • 100% control valve authority lowers pump head and optimises energy consumption.
  • PICVs provide dynamic balancing in full or part load conditions - optimised control..

Applications:-

  • Fan Coil Units
  • Terminal Unit Applications
  • Chilled Ceilings and Beams
