Structural integrity of the Zebra air valve is enhanced by the pleated accordion design and integral heavy gauge frame construction. The effects of stratification have long been a concern to mechanical systems designers and building engineers. The Zebra precision air valve offers laminar airflow throughout its entire throttling range. The Zebra precision air valve's patented slide plates and direct-drive actuator mechanism provide precise throttling control. Due to its linear stroke and tight drive mechanism, Zebra 's slide plate design dramatically reduces linkage hysteresis and slide loading commonly found in conventional dampers.
Noise attenuation is accomplished by the use of an array of evenly distributed precision orifices.
The Zebra 's design is inherently quieter than single or opposed blade damper configurations.
