Fabric-reinforced molded diaphragms are widely used instead of interference seals and flat diaphragms wherever a relatively long piston stroke is needed, and where dynamic and break-away friction would adversely affect the speed, accuracy or repeatability of an operation, and /or where blow-by leakage cannot be tolerated.
Typical applications include high-accuracy positioning, fluid metering and a broad range of control functions in which reliability and long service life with minimum maintenance are critical.
Advantages:
Virtually no friction
No break-away friction
Fast response to small changes in pressure – accurate positioning
Minimum wear - minimum maintenance
No blow-by leakage
No lubrication needed
Zero spring rate
Disadvantages:
Generally higer costs than interference seals
Longer installation time, in some instancesc
