PP variable air volume butterfly valve
The variable air volume butterfly valve is a pressure-independent butterfly valve that is specially used for air supply and exhaust with high precision and high response speed < 1S) to intelligently adjust the required air volume. PP flame retardant material V2/0 level, passed testing and certification by a third-party agency, equipped with 2S fast actuator.

It is mainly used in laboratories with corrosive gas emissions and precise air volume requirements (not suitable for high temperature situations), such as fume hood exhaust, laboratory exhaust and supplementary air, animal room exhaust and supplementary air, etc.
