| STEEL EXHAUST AIR VALVES |
 |
STEEL EXHAUST AIR VALVES (SEV) are suitable for
use with all types of ventilating systems and offer an alternative low cost valve where
noise level, although important, is not critical. Adjustment of the airflow is achieved by
rotating the inner cone to the desired setting and is secured by means of a lock nut. Valves are available in 6 sizes to suit duct diameters of 08, 100, 125, 150, 160 and 200mm. The mounting ring is suitable for connecting to conventional ducting or for grouting into a wall and should be positioned to ensure that the front rim is flush with the finished wall face. The air valve has a quarter turn bayonet fastening which secures it firmly in place in the mounting ring. SEV valves are manufactured from steel spinnings, protected by a gloss white stove enamelled paint. The outer body is fitted with a gasket to form an airtight seal with the mounting ring. The mounting ring being made from plated steel. |
