Diaphragm seal with flange connection R series

with threaded connectionfor pressure gauges

R Series diaphragm seals feature removable metal diaphragms that can be replaced or repaired as needed over time. The diaphragm is self-retained in the upper housing for easy repair or replacement. This extends the life of the seal element and allows for easy field replacement and service. Type R Series seals have low operating costs and greatly reduce the need to completely replace the entire seal element, even in harsh applications. Type R Series diaphragm seals employ a diaphragm retained between two bolted members. In the clean-out design, the diaphragm is situated between the top and middle ring. In the plain design, the diaphragm is located between the top and bottom. Type R Series diaphragms have integral gaskets with a baked-on TEFLON® finish. A VITON O-ring also seals the fill fluid cavity. The seal element’s upper housing is contoured to allow maximum movement and minimal distortion due to improper handling. Type R seal elements have a volumetric displacement of .07 cubic inches. Threaded Seal Eléments There are four basic versions of R Sériés diaphragm seals with threaded attachments. The RB seal element is used for pressure applications only and has a standard pressure rating of 2500 psig (optional 5000 psig) at 100°F (38°C). The RG seal element is similar to the RB seal, except that it has a 1/4 NPT flushing connection and optional 3000 psig rating. The RA seal element has a standard pressure rating of 2500 psig at 100°F (38°C), but may also be supplied with a pressure rating of up to 5000 psig. The RH seal element is similar to the RA seal element except that it features a 1/4 NPT flushing connection and optional 3000 psig rating.
