General information

Features and applications

GN 722.1 lever indexing plungers are used when the plunger must be retracted quickly.

By rotating through 180° the lifting lever stops on the notch, keeping the plunger in the retracted position.

AISI 316 stainless steel is suitable for use in particularly aggressive environments.

The dimensional tolerances between plunger pin and guide are selected so that the functional reliability is guaranteed even after welding, applying a corrosion protection layer or in case of contamination.

In the case of fixing by welding, the unassembled AU version is particularly recommended to avoid alterations to the microstructure of the material due to the heating of the spring and the plunger. In this case, the spring indexing plunger is assembled only after the surface treatment of the welded guide.
