Electronic rectangular flow regulator for VAV/CAV applications. “Pressure independent” electronic regulation, with measurement of the instantaneous flow rate by means of a speed probe and differential pressure transducer. Control signal 0-10 Vdc (or 2-10 Vdc) proportional. Possibility of forcing the state of the regulator by means of mandatory commands: "all open", "all closed", "maximum flow", "minimum flow". Flow monitor function for viewing the instantaneous value remotely. Master-slave function for overpressure/depression control applications (models BP1 or BP2). Damper with silicone gasket along the fins (class 4/C sealing according to EN 1751). Can be used for both supply and return, placing the measuring ring (pressure probe) upstream from the damper. Regulation with Belimo (FVA-RB▢) or Siemens (FVA-RS▢) motor.

Available executions

• FVA-R ▢: standard execution
• FVA-RI ▢: like FVA-R ▢ but with with insulating cap applied externally, to attenuate the radiated noise
• FVA-R▢ spec.013: stainless steel execution

▢ = type of engine (see code in the table)

Accessories

• SIL-FVA-R: rectangular silencer for FVA
• BA-FVA 2R: 2-row post-heating (water) coil
