Wndf type plug-in constant air volume valve is composed of valve body, valve plate, reed, air bag and movable baffle. When the air volume in the pipeline increases or the air supply pressure increases, the air bag will reduce the valve opening, and reach a balance with the reed tension, so as to maintain a constant supply of air volume. The action response is sensitive and quick, and the position of the movable baffle is easy to adjust. Different positions correspond to different constant air volume. Users can make simple adjustment to the combined air volume according to the actual needs on site. The quality of the whole valve body is light and firm, and the installation is more convenient. When leaving the factory, the air volume has been adjusted and passed the air volume test according to the user's requirements, and it is equipped with an internal sealing ring. The user only needs to insert it into the air duct and make a simple fixation, and then it can be put into use.
