Radial spring arrangement permits a low mounting height

Low volume between diaphragm and case gives fast response times

Strong operating force by permissible pressure supply up to 6 bar / 87 psig

Permissible ambient temperature -40 up to 80°C, operating in the limits temporarily allowed otherwise lifetime will be reduced

Fabric-reinforced, roll-type diaphragm with minimum area variation allowing linearity to be maintained throughout various stroke positions, even upon loss of operating forces

Positioner direct mounting without tubing (spring to close)

Safety Integrity Level (SIL) 3 Capable
