Pressure and Temperature Measurement • Diaphragm Seals
All Welded Metal Flush Flange Diaphragm Seal
SFX Series DESCRIPTION
The SFX Series seal elements feature a one-piece, all welded construction with an integrated raised face ANSIB16.5 class flange seal, surface machined into the upper housing. The seal’s unique design allows for easy installation and maintenance. The design permits free movement of the diaphragm with simultaneous response to pressure changes. It also protects the seal element from distortion due to improper handling during maintenance routines.
FEATURES D
• Self cleaning flush diaphragm face makes this series ideal for viscous process environments
• Ideal For Gas and Liquid Applications • One-piece construction
• Built-in over pressure protection (continuous duty diaphragm profile) • Designed for corrosive applications • Easy installation and maintenance • Continuous duty • All-welded construction • No gaskets • ¼” and ½” NPT instrument connections • Flanged attached process connection • ANSI B16.5 compliant
• Compatible with most transmitters, transducers, pressure switches, pressure gauges, etc. Welded Metal Diaphragm Seals for Jacked
Pipelines SMJ and SNJ Series DESCRIPTION
These seal elements are used in applications where there is a jacketed pipeline and where heated or cooled processes are involved. The SMJ Series conforms to Schedule 40 process pipe rating (other schedules available). SNJ seals meet ANSI flange pressure/temperature ratings.
