PP air valve

The full name of PP air valve is PP air volume regulating valve, which is used to regulate the air volume in the exhaust pipe of waste gas treatment. It is acid and alkali resistant. A diameter of 315 or less is a one-time molding air valve, while a diameter of 315 or more is manually processed and made. PP air valve is an accessory of PP air duct and is indispensable in exhaust engineering. In the case of multiple exhaust outlets, due to different pressure losses in the pipeline and changes in air volume, each outlet cannot guarantee the same air volume. Therefore, the installation of PP air valve and outlet plays a role in adjusting the section of the outlet and maintaining a constant air speed and volume.
