  • Saunders Industrial Diaphragm Valves

Diaphragm Valves
PK Saunders invented the diaphragm valve in 1928. In succeeding years have developed a range through innovation in both design and new materials technology. As a result, Saunders diaphragm valves have gained an excellent reputation worldwide for versatility and reliability in Aseptic and in Industrial applications with corrosive and abrasive media. We offer four main types of diaphragm valve, each type specifically suited to these applications.
  • Saunders Weir Type A Diaphragm Valve (for Industrial and Corrosive duties)
  • Saunders Straight Through Type KB Diaphragm Valve (Abrasive Duties)
  • Saunders WFB Diaphragm Valve (for Marine & Hydrant duties)
  • Saunders Aseptic Diaphragm Valves (for Biopharmaceutical duties)

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

The diaphragm is the key performance component within a diaphragm valve providing leaktight shutoff downstream and to atmosphere, also, isolating the topworks form the process media. As the innovator and leader in diaphragm valves, we continuously develop our diaphragm technology and remain 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 media’s.

For those using Saunders diaphragm valves in Biopharmaceutical applications, our range of diaphragms is 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) Chapter1 Title 21, with testing and certification to USP Classes V and VI. Certificates of Conformity are also available.
