Product news

  • Saunders Aseptic Diaphragm Valves

    PK Saunders® invented and patented the diaphragm valve concept long before the emergence of the Life Science industry. However, the design features present in the original weir type diaphragm valve remain the reasons the aseptic diaphragm valve is recognized as the valve of choice for aseptic applications.

    PTFE Diaphragms

    Saunders® Life Science PTFE diaphragms are robust two piece leaf type. This design uses a wetted PTFE face backed with a fabric reinforced rubber diaphragm. Critical performance factors include: resistence to compression set, mechanical strength, and thermal resistance properties.

    Saunders® has front-to-back ownership of all phases of diaphragm development and manufacture. This includes the sintering and coining of PTFE diaphragm faces as well as the compounding, calendering and compression molding of elastomer diaphragms and backing cushions.
