Product description

Indexing plungers GN 8170 are certified according to DGUV Test and, with their additional sealing lock nut, meet hygienic requirements on the knob and pin side. Wipers between knob and threaded body and between threaded body and pin as well as sealing rings on the threaded body and sealing lock nut keep the mechanics sealed. The high surface quality (Ra < 0.8 µm) and the free of dead-space mounting prevent dirt from adhering and facilitate cleaning.

Indexing plungers with lock-out (type C) are used for applications where the plunger pin needs to stay in its retracted position. To achieve this, the knob is rotated by 90 degrees after being retracted. A notch keeps the plunger in the retracted position.

Through-holes in the housing must be drilled at a right angle, free of burrs and without a chamfer. This ensures that the sealing rings will function after being mounted.
