Relation between line pressure and spring sets
The closing force of the actuators were designed for the specified PN rating.
Operation with low line pressure and very strong actuators can cause increase
diaphragm wear. For example, only use DIASTAR Sixteen (FC) if media pressure
> PN 6. In order to extend the diaphragm life span with low line pressure, the
number of spring packages can be reduced.
DANGER
Personal and/or material damage by reducing spring sets!
Reduced spring sets lead to a reduced closing force. At a rising line
pressure the valve cannot close or not close properly due to missing spring
sets. Death or serious injury could occur due to open piping. The process
can be influenced negatively.
 Configure diaphragm valve and actuator according to your line pressure.
