Light gauge ducting systems
Longitudinally stitch-welded throttle valves with a material thickness of 1 mm with an inner blade with a material thickness of 3 mm 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 rotating actuator model is a LMC for the throttle valves Ø80 up to Ø160, and SM for the throttle valves Ø180 up to Ø800. Axle seals are used and a natural rubber gasket is applied to the valve blade for better airtightness.
