Swagelok® Bulk-Gas Diaphragm Valves (LD Series)
LD series bulk gas diaphragm valves offer a combination of strength, flexibility, and cycle life to support a wide range of ultrahigh-purity shutoff, bulk-gas distribution, and isolation applications.Request More Information
LD series diaphragm valves have a welded diaphragm construction using three diaphragms welded to the stem to prevent leakage. No use of springs or threads in wetted areas enable cleaner operation, and a unique stem tip design promotes leak-tight shutoff. Flow coefficients up to 13 and a variety of body materials and configurations are available to meet a range of design specifications.
