FLANGED OFFLINE WELDED DIAPHRAGM SEALS

REOTEMP’s Flanged Offline Welded Diaphragm Seals are designed with an upper and lower housing, bolted together with a diaphragm welded to the upper housing. This removable design allows for easy cleanout of the seal chamber, while maintaining the system fill. The flanged offline diaphragm seal can be adapted to fit almost any pressure instrument and process application.

  • Welded Diaphragm for Maximum Durability
  • Wide Variety of Diaphragm and Material Options
  • Continuous-duty Disc Protects from Process Fluid Leaking in the Event of a System Breach
  • Easy Cleanout of Diaphragm Cavity without Compromising Filled System
