PTFE: When you need a material that works in harsh environments.
But what if your application involves working with harsh chemicals such as heptane or methyl chloride? PTFE is the material of choice.
Here is the challenge: PTFE is not an elastomer. It doesn’t stretch when the actuator pushes on it and it “cold flows” at the seat with the valve. As a result, designing a PTFE radial diaphragm that doesn’t leak has been extremely difficult, to say the least. But we have finally succeeded!
PTFE diaphragms for ASEPCO tank valves are now available in 1 inch, 1.5 inch, 2 inches, and 3 inches. Due to the difference in how the material handles during actuation, existing actuators need to be modified if you want to move to PTFE.
Give us a call, we’d love to help you solve any challenge you might have.
