Extract Valves


The HEV extract valve offers an efficient way of extracting air, with excellent performance characteristics and a stylish design for most commercial, industrial and residential ventilation applications. The airflow rate of the HEV can be adjusted by simply turning the inner cone either inwards (clockwise) or outwards (anti-clockwise). The inner cone is secured with an integral locknut which ensures the set airflow is maintained.
