The Helios KTV 75/80 and KTVA 75/80 air valves are designed for both air intake and exhaust applications in rooms without specific fire protection requirements. Manufactured entirely from anti-static polymer, these valves offer excellent corrosion resistance and are suitable for use in environments with temperatures up to 100 °C.
Airflow is easily adjusted by rotating the valve disc to the desired setting. Installation is quick and straightforward using integrated spring clips, which secure the valve in place with a simple push into the duct or wall opening. These models are ideal for lightweight, corrosion-resistant ventilation solutions in residential and commercial settings.
