Radial Diaphragm Valves—DR Series
The Swagelok® DR series radial diaphragm valve offers a cleaner, more compact way to manage sterile flow streams for many applications: media preparation, fermentation, harvest, separation, refining, purification, CIP, and SIP systems. The single-body biopharm valve design can be manufactured in a wide range of configurations to include multiple valves and multiple ports, and point-of-use valves. A single Swagelok radial diaphragm valve can replace complex weir-style valve assemblies, resulting in a more compact system.
