SVA-R

Product catalog summary

Introduction
The SVA-R rectangular VAV dampers by MADEL are designed for Variable Air Volume (VAV) installations. These dampers adjust airflow to a bypass or room based on a 0-10 V signal from a temperature controller. The flow can be adjusted post-installation using a remote control.

Classification
The SVA-R dampers are classified by their maximum (Vmax) and minimum (Vmin) airflow settings, calibrated at the factory per customer specifications. They operate in Master or Slave modes and support 0-10 V proportional or 3-point control. They also feature thermo-acoustical insulation.

Material and Construction
The dampers are constructed with a galvanized steel housing, aluminum for cross differential pressure measurement, ABS connections, and silicone measuring tubes. The damper foam seal is made from EPDM.

Accessories
Available accessories include the RDG 400 (SIEMENS) and CR24-A1 (BELIMO) proportional temperature controllers, which support 0-10 V power supply and feature a backlit digital display. The RDG 400KN and CR24-B1 models include KNX communication for integration into Building Management Systems (BMS).

Specifications
The dampers are supplied and mounted with cross differential pressure measurement for airflow adjustment. They are available in various sizes and configurations, with specific models for Master operation and 0-10 V proportional control.

Installation Guidelines
Ensure uniform airflow to the damper and avoid installation in areas with vibrations. The inner dimensions of air ducts should not be smaller than the damper's dimensions.

Technical Data
Technical specifications include a 24 V AC/DC power supply, power consumption of 3.5 W / 6VA, and compliance with EN 60730 and IP54 standards. The dampers are CE certified according to 89/336 EEC.

Sound and Noise Levels
Sound pressure levels are provided for various duct sizes and velocities, with data on ducted and irradiated noise levels at different pressures (100Pa, 300Pa, 500Pa). Sound attenuation and correction factors are also detailed.

Electrical Connections
Standard electrical connections for SIEMENS and BELIMO controllers are outlined, including wiring diagrams and technical data for each configuration.

SVA-R rectangular VAV dampers Rectangular air flow damper for Variable Air Volume (VAV) installations. The SVA-R dampers are used to adjust the air flow to a bypass or a room based on a 0-10 V signal provided by a controller of temperature. The command signal sent by the controller of the room, position the actuator to control the flow of the need the enclosure. You can change a posteriori the flow Vmin and Vmax using a remote control.
