Pneumatic diaphragm valve

  • Application range

    Biopharmaceutical, food and beverage, fluid equipment, cosmetics, brewing, light chemical industry, etc.

  • Characteristics

    1. Patented stem structure with double guiding rings ensures more stable operation. 

    2. Patented spring seat design allows effortless maintenance.

    3. Patented design allows valve stem and core to connect via internal concave surface and thereby ensures tight sealing.

    4. ESG diaphragms have passed FDA and USP certifications; ESG diaphragm valves have passed EU EC 1935-2004 certifications.

    5. Can be installed at any pipe location. Medium flow direction does not affect valve opening/closing.

    6. ESG PTFE diaphragms are capable of withstanding 1 million bending test cycles.
