Light gauge ducting systems
Longitudinally stitch-welded throttle valves for use in overpressure, under-pressure and pressureless systems.
The valves are provided with an electric rotating actuator which opens or closes the blade. The open/close time is 30 seconds.
Axle seals are used and a natural rubber seal is applied to the valve blade for better airtightness.
Rolled sheets, stitch-welded, with 6 mm edges for lock rings.
