Replaces Wilden® 00-1080-55
PTFE is the most chemical resistant of all the diaphragm materials. It is good for handling strong acids, alkalis (caustics), and solvents. Because of its greater stiffness, it significantly increases required closing/sealing forces. TFE has a shorter working life than elastomer diaphragms and may require a larger actuator size on automatic valves.
