Type 40 Flow-Through Annular Style, Replaceable Diaphragm Seals

 

 

  • Process liquid flowing through the pipe exerts pressure onto a flush-mounted
    flexible inner cylinder containing clean, captive liquid; completely isolating
    instrumentation from the process flow and preventing plugging
  • Can be used for remote mounting of pressure instrument(s) with capillary
  • Instrumentation can be removed for calibration, repair or replacement without
    interrupting the process flow
  • Integral design prevents accidental breakage
  • Can be used with a variety of process conditions in many applications
  • Eliminates clogging typically associated with diaphragm seals used in viscous
    fluid applications which can lead to inaccurate pressure readings
  • Assembly flanges ASME B16.1 Class 150, 2" to 20"
