MA 08 - EPDM - SED Diaphragm

SED Diaphragms

The SED EPDM diaphragm consist of a specifically developed compound reinforced with vulcanized woven fabric inlay. This construction gives it higher stability at elevated temperatures and pressures, such as in critical aseptic apllications with SIP steam sterilizing cycles and processes.

MA8, as the only diaphragm in de complete EPDM serie, is connected with the valve operating mechanism by an elastomer button (button fixed). 
The SED EPDM diaphragm is always manufactured in the molded open position.


  • Woven fabric reinforcement between two elastomer layers
  • Increased lifetime expectancy under steam
  • Ideal for vacuum applications
  • “cross” weir contour
  • One piece, molded open
  • Diaphragm is interchangeable with all SED diaphragm valves
  • Clearly indentified, material is batch traceable by a set of unique codes molded into the diaphragm dvary
