Aseptic Diaphragm Valves

Simplicity in design coupled with over 75 years of cutting edge innovation has resulted in the Saunders Diaphragm valve’s ability to handle a wider range of fluids than any other valve type.

Saunders continues to lead the diaphragm valve industry in the development and manufacture of elastomer components based on in-house core competence in rubber and plastic technologies.

The diaphragm is the key performance component within a diaphragm valve providing leak tight shutoff downstream and to atmosphere, also isolating the topworks from the process media. As the innovator and leader in diaphragm valves, Saunders continuously develops diaphragm technology and remains the only manufacturer to have front to back ownership of all aspects of polymer research and development , rubber technology, diaphragm design and production.

For our customers involved in Chemicals processing and related industries including power generation, water treatment, effluent treatment, Chlor-Alkali, minerals processing and metal treatment, we offer a full range of diaphragms suitable for handling a wide variety of corrosive, abrasive and combined corrosive/abrasive medias.

For those using Saunders diaphragm valves in Bio-pharmaceutical applications, our range of diaphragms are engineered to meet the exacting demands found within the industry. This includes batch traceability to aid the validation process, diaphragms manufactured from FDA conforming materials to meet the requirements of CFR (Code of Federal Regulations) Chapter 1 Title 21, with testing and certification to USP Classes V and VI. Certificates of conformity are also available.
