What is PTFE diaphragm?

PTFE diaphragm

PTFE (+EPDM or FKM support sheet) double-layer diaphragm is a high-standard diaphragm form used in sanitary diaphragm valves internationally, and it is the most reliable product for production workers who frequently use SIP sterilization. Widely used in blood products, vaccines, biopharmaceuticals, large and small volume injections, aseptic production, fermentation, water for injection supply and distribution circuits and other fields.

The EPDM or FKM support on the double-layer diaphragm not only protects the PTFE diaphragm in contact with the product, but also strengthens the sealing effect of the PTFE diaphragm. The reliability and service life of the PTFE double-layer diaphragm will reach the best level.
