Saunders® HC4 Diaphragm Valves

The aseptic diaphragm valve is the most important control component in today’s biopharmaceutical process systems. As the inventor of the diaphragm valve, Saunders has been a key player in the evolution of high purity valve technology. Beginning with the introduction of forged bodies and compact thermoplastic actuators through to today’s machined from solid compound and multi-port valve solutions; we have taken the lead in aseptic valve technology.
