The MEV Series Toilet Exhaust Valves are designed for effective air exhaust in applications requiring low airflow movement, particularly in circular duct systems. These valves feature an adjustable central disc that can be moved inward or outward, allowing precise control over the airflow passage and enabling the volume to be regulated based on specific ventilation needs.

Engineered to provide high initial resistance and excellent throttling capability, the MEV series is ideal for systems with relatively high resistance levels. Their functional design ensures efficient performance in washrooms, restrooms, and other low-ventilation spaces, making them a practical and reliable choice for controlled exhaust air applications.
