Ravenscroft provides Halton ULA supply air and exhaust valves for ceiling and wall installation with adjustable pressure loss.
ULAs can be installed without an installation frame directly into ductwork or a hollow-core slab.
In supply air application the desired flow pattern is directed using an internal sector plate. The desired pressure loss and airflow rate can be adjusted in an exhaust air application, by removing the sector plate and adjusting the front panel position.
