- Batch traceable by a set of unique codes molded into the diaphragm dvary.
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.
The PTFE MA 8 consists of a separate EPDM backing cushion and a PTFE diaphragm. It is designed as a one-piece diaphragm, which means that the EPDM backing is bonded with the PTFE. The diaphragm is always manufactured and molded in the open position. These one-piece diaphragms have less surface area and are subject to shorter linear strokes. The MA-8 diaphragm incorporates an elastomer button for assembly with the valve operating mechanism. This eliminates the potential for point loading at the center of the diaphragm.
