Vernay Diaphragms are engineered to provide quality performance at specific pressures, even under the most demanding environments. Because of their unique design, Vernay Diaphragms perform complex tasks in mechanical, fluid, and gaseous applications easily and economically. They provide optimum sensitivity and the strength to withstand significant pressure change. Vernay specializes in convoluted diaphragms, thin wall diaphragm, rolling diaphragms, general diaphragms, servo action diaphragms, and inserted diaphragms.

Used to convert pressure to force/stroke or vice versa
Provides a fluid (gas or liquid) seal between the two sides
May have a rigid center section to give more "piston-like" action
Total stroke needed impacts the design of the convolute
Material may be critical for chemical attack, gas permeation, and life
