Dynamic HVAC flow control with dynamx™ 6-port control valves (PICV)

The BELPARTS 6-port valve is an advanced control valve designed specifically for variable flow HVAC systems. This control valve offers seamless switching between heating and cooling. The control valves are well suited for use with air conditioning ceilings and fan coil units in offices, schools, hospitals and commercial buildings, among others.

How exactly does the dynamx™ 6-port control valve work?

The 6-port flow control valve uses advanced technology to accurately control flow. The integrated flow sensor continuously measures the current flow rate, while the internal controller compares it to the desired flow set point. The control valve automatically adjusts to pressure fluctuations, ensuring maximum comfort and minimum energy consumption.

What makes the dynamx™ 6-port control valve so special?

  • 5-in-1 solution: combines the functions of a changeover valve, a balancing valve, a pressure independent control valve, a shut-off valve and an optional room temperature controller in one component.
  • Pressure-independent dynamic flow control: provides accurate and stable flow control, independent of pressure fluctuations in the system, both at full and part load.
  • Integrated flow measurement: continuous measurement and control of flow rate ensures optimum performance and energy efficiency.
  • Wireless commissioning via Bluetooth®: easy and fast commissioning via the app on your smartphone or tablet. Even with closed ceiling panels, thanks to integrated Bluetooth® communication.
  • MP MultiProtocol Communication: support for MODBUS RTU and BACnet MSTP, allowing easy integration into any building management system (BMS).
  • Dynamic Flow Networking® (DFN): provides perfect hydraulic balance without additional components, eliminates the need for static balancing valves and offers automatic balancing instead.

The dynamx™ 6-port control valves operate as switching between heating and cooling, where the set design flow rate can be infinitely controlled between 0..Vmaxh (heating) or 0..Vmaxc (cooling).

Climate ceilings in combination with a dynamx™ 6-port control valves

Climate ceilings that provide both heating and cooling through ceiling tiles are popular because of their efficient use of space and their ability to provide even temperature distribution. dynamx™ 6-port control valves are particularly suitable for climate ceilings for the following reasons:

  • Dual function: switches between heating and cooling, which is essential for the operation of climate ceilings.
  • Design-flow for heating and cooling: can be set separately in one and the same valve. The wide control range of Belparts 6-port control valves makes it very easy to set totally different maximum flow rates for heating and cooling, which is inherent to the design of any installation.
  • Automatic balancing: ensures optimal hydraulic balance, which is important to ensure the performance of climate ceilings without manual adjustments.
  • Real-time flow control: provides precise control and adjustment of flow rate, which is important for maintaining a comfortable indoor environment.

FAQ

A 6-port control valve is designed for 4-pipe heating and cooling systems and allows a single terminal unit, such as a fan coil unit, chilled beam or radiant panel, to switch between heating and cooling circuits. The valve automatically manages changeover and modulates the water flow to match the actual demand, ensuring precise temperature control and optimal system efficiency.

A 6-port control valve can replace multiple conventional valves and balancing components with a single compact solution. This reduces installation time, simplifies commissioning, lowers material costs and minimizes potential leakage points. In addition, pressure-independent flow control helps maintain stable performance and improves overall energy efficiency.

6-port control valves are commonly used in commercial buildings with simultaneous heating and cooling requirements. Typical applications include fan coil units, chilled beams, radiant ceiling systems and other HVAC terminal units connected to 4-pipe systems. They are particularly suitable for projects where energy efficiency, occupant comfort and simplified hydraulic balancing are important design objectives.
