Pneumatic UPVC Double Union Diaphragm Valve employs a dedicated diaphragm to separate the upper and lower valve cavities, protecting internal components such as the stem from corrosive media. This structure removes the packing seal design to avoid external leakage, and soft sealing diaphragms ensure stable and dependable sealing performance in fluid handling systems.
