Description

Type S Series diaphragm seals feature a metal seal diaphragm, which is permanently welded onto the seal element’s upper flange. This design eliminates the need for a diaphragm retaining ring and minimizes the risk of fluid leakage during normal operation or seal element maintenance. These seal elements feature an upper housing that is contoured, which permits free movement of the diaphragm with an accurate response to pressure changes. It also protects the seal element from distortion due to improper handling during maintenance routines. Type S Series diaphragm seals have a volumetric displacement of .07 cubic inches. Filling screws are standard on all models. Welded metal seals are ideal for general-purpose applications with ranges from 60 to 2,500 psi at 100°F (1 to 176 bar at 38°C). Optional ranges are available up to 5000 psi (345 bar). FEATURES • - Diaphragm directly welded to upper flange - - Eliminâtes retaining ring - - Minimizes risk of leaks • - Idéal for general purpose application • - Materials available for corrosive applications • - Optional seal ratings to 10,000 psig (690 bar) • - Compatible with most 4-1/2” and smaller gauges SEAL CONFIGURATIONS Threaded Seal Eléments There are four basic versions of S Sériés diaphragm seals with threaded attachments. The SB seal element is used for pressure applications only and has a standard pressure rating of 2500 psig at 100°F (172 bar at 38°C) with an optional rating for up to 5000 psig (345 bar). The SG seal element is similar to the SB seal, except that it has a 1/4 NPT flushing connection. The SX seal element has a standard pressure rating of 10,000 psig at 100°F (690 bar at 38°C).
