Belparts terminal control valves for zone control

To regulate the water temperature in HVAC systems based on heating or cooling needs, a terminal control valve is used. They control the water temperature for HVAC terminal units, such as fan coil units, climate ceilings and induction units, which affect the temperature in different zones and improve the comfort level in a building. Belparts terminal control valves can have either a thermal actuator or an electric actuator. Thermal actuators are a simple and reliable way to operate terminal control valves.

Benefits of Belparts readjustment valves

  • Compatible with any control system: whether you use a building management system (BMS) or another control system, Belparts drives are suitable for integration into existing infrastructures.
  • Pluggable assembly: easy installation and ease of maintenance.
  • Position indication : clear visual indication of valve position.
  • ‘First open’ function: this function ensures that the valve is first fully opened before being moved to the desired position.

Advanced 6-port valves, series N6

For HVAC systems that need both heating and cooling, such as in contemporary buildings with adjustable climate control, switching between heating and cooling is crucial, for example with climate ceilings. Belparts 6-port control ball valves are made for this purpose. They have a special built-in overpressure protection device, which stops the system pressure from going over a certain limit.

Belparts terminal controls help adjust rooms precisely

Measuring temperature, humidity, pressure differences and air quality is important for comfort in a building. You can control individual rooms with terminal controls. This way, the temperature and other factors match the users’ needs. Belparts terminal controls have different designs and work well with climate ceilings, VAV (Variable Air Volume) systems, underfloor heating and other HVAC systems. The terminal controls are customized for each building and room. You can connect them to a building management system with a MODBUS or BACnet link.
