Louvre Valves

MID’s Louvre valves are commonly used to throttle the airflow in dust extraction or pneumatic conveying systems, or general applications where a controlled airflow is required to maintain a process condition such as the temperature within a kiln.

They can also be used to provide a ‘low headroom’ shut off to the flow of powders or can be used in applications where the lack of surrounding space prevents the use of a slide valve or knifegate valve.


Available with either square or rectangular inlet/outlets, up to a maximum of 2m, in either carbon steel or stainless steel.

Carbon steel versions come with zinc plated louvres and shafts.

As standard, the valve is suitable for temperatures up to 200°C. Please ask if you need a higher temperature.

Open/closed switches for pneumatic valves. Also available for manual.
