Product description


GN 8170 Stainless Steel-Indexing plungers are intended for use in hygienic areas. The wiper between the pin and guide keeps the mechanics sealed, and the high surface quality and dead-space-free mounting prevent dirt from adhering and facilitate cleaning.

The type FH satisfies hygienic requirements on the knob side. For uses in which the bolt is also subject to hygienic requirements, the type VH is used. Mounting holes and through-holes in the housing must be at a right angle, free of burrs and without a chamfer. This ensures that the sealing rings will function after being mounted.

Indexing plungers with a rest position are used for such applications where the plunger has to stay in its retracted position. In that case, the knob is retracted and afterwards turned by 90°. A notch keeps the plunger in this position.
