Pneumatic diaphragm valve

  • Application range

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

  • Characteristics

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

    ■Patented spring seat design allows effortless maintenance.

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

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

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

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