Structural characteristics of the air valve</strong></p><p>(1) The <a href="https://ppairvalve.com/shop/air-flow-control-fittings-pp-butterfly-valve-2/">air volume control valve</a> has four specifications when the blade width is all the same. The blade shape is a diamond-shaped double blade, and the blades are soft overlapped, so the sealing performance is excellent.</p><p>(2) The valve body frame of the air volume control valve is injection molded from polypropylene material, which has good sealing performance. The product itself has the characteristics of anti-acid and alkali corrosion, and can be widely used in exhaust gas exhaust pipes.</p><p>(3) The dispatch valve is divided into manual and electric. The valve body structure and specifications are the same.</p><p><strong>2.the characteristics of the air valve</strong></p><p>(1) The takeover standard of the split multi-leaf air volume dispatching valve is the same as the rectangular air duct standard of the national ventilation duct standardization.</p><p>(2) The blades of the air volume dispatching valve are side-opening and forward-opening, which are used as dispatching valves in ventilation, air dispatching and air purification systems.</p><p>(3) According to the test, the air-tightness of the air volume dispatching valve is good, and its relative air leakage is about 5%, and the dispatching performance is good.</p><figure class="wp-block-image size-full"><img decoding="async" width="800" height="800" src="https://ppairvalve.com/wp-content/uploads/2022/01/Hed78584dbe6d49e0a60fa587ad3ebeaej.jpg" alt="" class="wp-image-674" srcset="https://ppairvalve.com/wp-content/uploads/2022/01/Hed78584dbe6d49e0a60fa587ad3ebeaej.jpg 800w, https://ppairvalve.com/wp-content/uploads/2022/01/Hed78584dbe6d49e0a60fa587ad3ebeaej-300x300.jpg 300w, https://ppairvalve.com/wp-content/uploads/2022/01/Hed78584dbe6d49e0a60fa587ad3ebeaej-150x150.jpg 150w, https://ppairvalve.com/wp-content/uploads/2022/01/Hed78584dbe6d49e0a60fa587ad3ebeaej-768x768.jpg 768w, https://ppairvalve.com/wp-content/uploads/2022/01/Hed78584dbe6d49e0a60fa587ad3ebeaej-600x600.jpg 600w, https://ppairvalve.com/wp-content/uploads/2022/01/Hed78584dbe6d49e0a60fa587ad3ebeaej-100x100.jpg 100w" sizes="(max-width: 800px) 100vw, 800px" /></figure><p><strong>3.the scope of application of the air valve</strong></p><p>It is widely used in industrial, mining, and civil building HVAC systems to accurately schedule air flow. It is one of the key equipment for controlling ventilation modes in various environments. Its main features are flexible work, low noise, small leakage, reliable structure, safety and convenience.</p><p>The above are the main functions and features of the air valve. There are also different types of <strong>air valve</strong> for different occasions and needs.</p><ul class="wp-block-list"><li>Contact information</li><li>Email: Leyte@chian-xicheng.com</li><li>Whatsapp: +86 19925135783</li></ul>]]></content:encoded>
