VRW (round) and VRX (rectangular)

VRWdampers are self-operated constant flow rate controllers (without auxiliary power supply). Flow control is obtained through an asymmetrically angled regulating blade on friction-free bearings, ensuring a precision response and regulating action even at low flow rates.
The constant flow rate controllers are delivered with the reference flow rate set in the factory.
The target flow rate is set by the client on site. The flow rate can bemanually changed by the customer at any time with a hexagon socket wrench (2 mm) and read on a scale.
