VAV (flow variators)

Flow control devices for constant and/or variable flow systems. They consist of an external rectangular casing with a regulating blade and pressure sensing device. The blade is actuated by a 24 V servo-control unit equipped with a differential pressure sensor and an electronic measuring and control unit with microprocessor.

The flow rate is calibrated at the factory but can be changed by the user via the control unit.
