The VATTEN pneumatic flanged diaphragm valve features an innovative design that eliminates the need for a separate valve stem packing seal structure. The diaphragm itself performs dual functions: it not only effectively shuts off the medium flow but also protects the valve stem from the effects of the medium. The diaphragm is highly flexible, ensuring stable sealing performance across a wide range of conditions, even when dealing with dirty fluids containing particles or impurities.
Additionally, the simple structure of the VATTEN pneumatic flanged diaphragm valve reduces the need for maintenance and component replacements typically associated with traditional valves. This design minimizes long-term operational costs and complexity, while extending the valve's service life, even in harsh environments.
