In industries such as biopharmaceuticals, food & beverage, and high-purity water treatment, where sterility and residue-free performance are extremely critical, traditional valves can often create contamination risks due to structural dead zones or sealing failures.
That is why the sanitary diaphragm valve was developed. This product features a 316L stainless steel valve body and a mirror-polished flow path with Ra≤0.4μm. Combined with EPDM and PTFE diaphragms, it completely isolates the valve stem from the medium, effectively preventing leakage and cross-contamination.
Its unique straight-through or weir-type design eliminates grooves, gaps, and dead spaces, making it fully compatible with CIP/SIP online cleaning and sterilization. The diaphragm moves up and down to achieve bubble-tight sealing, offering excellent resistance to high temperature and corrosion while complying with international hygienic standards such as ASME BPE and 3-A.
Whether used for transporting vaccines, water for injection, or high-purity chemicals, the sanitary diaphragm valve provides a zero-dead-leg and leak-free structure, building a reliable safety barrier for every fluid process.
