    Diaphragm valve diaphragm

    Diaphragm valves have the advantages of high flux and low residue, and are widely used in fluid control in pharmaceuticals, beverages, food, and chemical industries. Their safety, reliability, and durability are inseparable from the performance of the diaphragm, which determines the lifespan of the diaphragm valve.
    PTFE diaphragm sheet is processed using high-temperature molding technology and has the characteristics of high density, high smoothness, and high bending degree. Its excellent high-temperature resistance can meet the requirements of SIP sterilization process
    This product is processed in a dedicated clean room and meets cGMP standard requirements
