Valve Lining
PTFE
Void-free body liner and disc isostatic molded from virgin
PTFE. High material density >2.16g/cm3. Guaranteed lining
thickness of at least 3mm plus high crystallinity. FDA compliant.
operating temperature
-40
°F up to +392°F
Abrasive PTFE
If the chemical resistance of PTFE is needed along with
abrasion resistance, then the use of abrasive service PTFE is
recommended. This special PTFE compound is
resistant to mechanical wear with almost the same chemical
resistance as virgin PTFE.

Antistatic PTFE
For explosive environments and medias, this electrostatically
conductive lining is available. The service life is comparable to
valves lined with PTFE. The material is FDA compliant. TUV
approval. (TUV 941 F 416 601).
