MA 40 - PTFE backed EPDM - 1-piece SED Diaphragm


SED Diaphragms

The diaphragm is the most important component of the diaphragm valve. Besides the valve body, the diaphragm is the only part which contacts the process medium. It is the dynamic part with which the flow rate of the process medium is controlled and/or stopped.

PTFE diaphragms offer the highest degree of chemical resistance, increased stability, longer flex life, less porosity, reduced cold flow, and superior performance through temperature fluctuations between hot and cold and steam sterilization cycles.

The PTFE MA 40 one-piece diaphragm consists of a seperate EPDM backing cushion bonded to a PTFE diaphragm. It is always molded in the open position. The threaded stud is connection is embedded in the PTFE of the diaphragm. 
All diaphragms are clearly indentified and the material is batch traceable by a set of unique codes molded into the diaphragm dvary.
