Diaphragms

How Do Diaphragms Work? 

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

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