PVC Ventilation Valve

Our PVC ventilation valves have chemical resistance and UV resistance, ensuring that they remain structurally complete and functionally stable during long-term exposure to moisture, acid and alkali or outdoor environments. The product is formed through precision injection molding. The overall structure is dense and sealed. It can effectively prevent air backflow and external pollutants from invading. It is suitable for various installation scenarios such as building roofs, walls, pipeline systems, and industrial exhaust equipment. Its lightweight but sturdy nature makes the installation process extremely convenient, without complex tools or additional support structures, and can be embedded directly into PVC pipes or vents for quick connection and secure fixation.

The product is available in a variety of standard caliber specifications, including D75, D110, D160, D200 and D250 mm, to meet the different flow requirements from small residential ventilation to large factory exhaust systems. Each specification undergoes rigorous stress testing and airtightness testing to ensure stable operation under continuous airflow shock. For example, the D75 model packs 140 pieces per box, which is suitable for high-density procurement and batch construction projects; the D110 model packs 60 pieces per box, taking into account transportation efficiency and flexibility of use; while the larger diameter D160, D200 and D250 models pack 30, 18 and 18 pieces per box, which facilitates orderly management and on-site distribution in heavy-duty projects. All products are packaged in anti-pressure damage cartons, and internal compartments are added to protect them to avoid deformation or scratches caused by collision during transportation.

In practical applications, the ventilation valve exhibits natural ventilation and regulation capabilities, relying on the air pressure difference to automatically turn on and close the valve plate, without electric power driving, and is energy-saving and environmentally friendly. The valve plate design adopts a one-way flip structure, with a reasonable opening angle and low airflow resistance, which can significantly improve ventilation efficiency and effectively prevent rainwater, dust and small animals from entering the pipeline system. The smooth surface of PVC material is not only easy to clean and maintain, but also has good flame retardant performance and meets the requirements of building safety regulations.
