A single Swagelok radial diaphragmvalve can replace complex weir-style valve assemblies,resulting in a more compact system.The DR series valve is designed for system pressures up to150 psig (10.3 bar) and operating temperatures up to 280°F(137°C).Extended Diaphragm Life■ Optimized diaphragm shapeminimizes stresses during cycling■ Uniformly distributed shutoff forceminimizes diaphragm distortion■ Modified PTFE diaphragm materialimproves thermal cycling performancePneumatic Actuators■ Choice of normally closed, normallyopen, and double-acting modes ofactuation■ Are offered in plastic or aluminum■ Are available with an optionalposition indicator switch assembly.Manual Actuators■ Feature a knob handle for 1/2, 3/4,and 1 in. sizes, and a hand wheel for1 1/2, and 2 in. sizes■ Provide positive shutoff with minimaltorque■ Open valve fully in 1 to 1 1/2 turns■ Are offered in plastic or aluminum.Live-Loaded Diaphragm ➀■ Controls cold flow of the modifiedPTFE diaphragm■ Maintains seal to body during thermalcyclingShown with pneumatic plastic actuator➀ 1/2 in. model maintains a seal without a liveloadeddiaphragm
