Radial Diaphragm Valve

Swagelok® DR Series radial diaphragm valve features new plastic pneumatic actuator, enhances caustic wash-down resistance. The patented radial diaphragm valve now is available with a polyethersulfone (PES) actuator, which offers excellent resistance to caustic wash-down. In addition, the live-loaded body seal controls cold flow of the PTFE diaphragm and maintains the body seal during cycling. Other benefits of the PES actuator include: high-quality material compliant with food and drug administration requirements; steam-in-place capability; and long cycle life. The plastic pneumatic actuator is available for use with stainless steel Swagelok DR series radial diaphragm valves in 1/2-, 3/4-, and 1-inch models. Swagelok DR series radial diaphragm valves minimize entrapment areas, drain easily, and clean completely. DR series valves can be manufactured in a wide range of configurations to include multiple valves and ports. This versatility can result in a more compact flow stream, built with less piping, a
