Swagelok® Bulk-Gas Diaphragm Valves (LD Series)
Swagelok 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.
Find More InformationSwagelok® LD series bulk-gas diaphragm valves are engineered for shutoff, bulk-gas distribution, and isolation services at working pressures up to 300 psig (20.6 bar). Three distinct diaphragms provide the ideal combination of strength, flexibility, and cycle life, while the all-metal design reinforces safety and durability.
Swagelok LD series valves also feature an innovative design that eliminates springs and threads in wetted areas, resulting in a cleaner operation and reducing contamination risks. In addition, the unique compensating stem tip design with a PCTFE insert promotes leak-tight shutoff and prevents damage from overtightening.
