These terms often describe similar concepts. The key factor is that in high-quality valves, both the valve disc and the seat ring, and in some cases the interior of the housing, are protected by a thick layer of PTFE. This ensures that all parts that come into contact with the medium are protected against corrosion.
Yes, absolutely. PTFE is FDA-compliant and therefore meets the strict requirements for use in the food and pharmaceutical industries. This guarantees the safety of your manufactured goods.
The continuous operating temperature range of our PTFE butterfly valves is typically between -25°C and +200°C. Some models can also tolerate higher temperatures for short periods.
Of course! Our experienced support team will be happy to advise you individually on housing material, seal type and drive. Simply contact us by telephone or email to find the perfect solution for your application.
Suitable for acids, alkalis, solvents and many oxidising agents, plus high-purity applications in chemical, pharma and food industries. Less suitable for highly abrasive solids/slurries and continuous temperatures above the PTFE limit. Check your medium first in the resistance tool.
