SVA-C

Product catalog summary

Introduction
The SVA-C circular 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 actuator positions itself to control the necessary airflow, and a foam seal ensures airtight closure when needed. Flow settings (Vmin and Vmax) can be adjusted remotely.

Classification
The SVA-C dampers are classified by their maximum (Vmax) and minimum (Vmin) airflow settings, calibrated at the factory. They operate in Master or Slave modes and support 0-10 V proportional control or 3-point control. Thermo-acoustical insulation is available.

Material and Construction
The dampers feature a galvanized steel housing with aluminum cross differential pressure measurement. Connections are made with ABS, and measuring tubes are in red/blue silicone. The foam seal is made from EPDM.

Accessories
Available accessories include the RDG 400 proportional temperature controller with a digital display and the RDG 400KN with KNX communication for BMS integration.

Fixing Systems
The dampers are designed for connection into circular metallic ducts.

Specifications
The specification text outlines the supply and mounting of the SVA-C dampers, detailing the materials and control modes.

Performance Data
The document includes tables and graphs showing recommended airflow, pressure loss, and sound power levels for various duct sizes and flow rates. Key data points include minimum and maximum airflow (Qmin and Qmax), pressure drop (Dpt), and velocity in the duct.

SVA C SVA-C circular VAV dampers Circular air flow damper for Variable Air Volume (VAV) installations. The SVA-C 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. A foam seal inside the perimeter of the damper seals the air in case of total closure order. You can change a posteriori the flow Vmin and Vmax using a remote control.
