The DR series valve minimizes entrapment areas, drains easily, maximizes cleanability, and provides extended diaphragm life. It provides a clean solution for many applications including media preparation, fermentation, harvest, separation, refining, purification, CIP, and SIP systems. Features Multivalve and Multiport Configurations Reduce overall system size Provide instantaneous flow shifts, reducing the potential for cross contamination Require fewer fittings and piping and less welding, making the system easier to validate Reduce or eliminate dead legs. The single-body 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. The DR series valve is designed for system pressures up to 50 psig (0.3 bar) and operating temperatures up to 280 F (37 C). Extended Diaphragm Life Optimized diaphragm shape minimizes stresses during cycling Uniformly distributed shutoff force minimizes diaphragm distortion Modified PTFE diaphragm material improves thermal cycling performance Pneumatic Actuators Choice of normally closed, normally open, and double-acting modes of actuation Are offered in plastic or aluminum Are available with an optional position indicator switch assembly. Manual Actuators Feature a knob handle for /2, 3/4, and sizes Provide positive shutoff with minimal torque Open valve fully in to /2 turns Are offered in plastic or aluminum.
