Frequently Asked Questions
Get answers to common questions about our PTFE & PFA lined ball valves
Certainly! We offer Antistatic PFA lined Valves in Dupont's grade C 980 or 3M Dyneon's 8502 ESDZ. Choosing the correct material is crucial, as a grounding spring alone cannot dissipate static charge in a standard PFA grade, which is non-conductive.
PFA lining offers high chemical resistance, a smooth surface that minimizes friction and fouling. The PFA lining acts as a barrier between the flowing medium and the valve's internal components, effectively shielding them from corrosive substances.
Yes, these valves generally require minimal maintenance. Regular inspection for wear and tear, along with routine cleaning, can help ensure their longevity
Our ball valves are available in numerous sizes DN15-DN300 (1/2"-12") providing a range of options to meet diverse industrial needs.
