Product Family Stainless Steel
Standard parts made of rustproof stainless steel have been designed for use in the food sector, in the chemical industry, for aggressive ambient conditions or for outdoor use.
Standard Parts of the “Hygienic Design” product family are labeled with the HD icon. They combine high surface quality, freedom from dead spaces, non-scooped outer surfaces, and sealed bolting areas. A sealing concept based on FEM calculations ensures reliable contact pressure after installation.
The FOOD AND DRUG ADMINISTRATION is a federal agency of the United States Department of Health and Human Services, one of the United States’ executive departments. The FDA is responsible for many things including food safety. The FDA has a positive list of substances that are allowed to come into contact with foods and beverages.
Indexing plungers GN 8170 are certified according to the DGUV Test and meet hygienic requirements on the knob side. Wipers between the knob and the threaded body as well as the sealing ring between the threaded body and the housing keep the mechanics on the knob side 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.
Mounting holes and 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.
