Is the DIN 11851 Stainless Steel DZK End with GZ, Notched Tail suitable for CIP/SIP cleaning at Ra 0.8 µm and up to 40 bar?

Yes. The DIN 11851 Stainless Steel DZK End with GZ, Notched Tail (Ra 0.8 µm inside the bore) is suitable for CIP/SIP cleaning and for the stated working pressures. The Ra 0.8 µm finish supports hygienic cleaning and minimizes microbial retention, and the stainless steel construction resists corrosion during CIP/SIP. Pressure ratings meet the specification: up to 40 bar for DN10–DN40, 25 bar for DN50–DN100, and 16 bar for DN125–DN150. Ensure gasket material used is compatible with your CIP/SIP temperatures and chemicals and rated for the process conditions to maintain seal integrity and full suitability.

Can the DIN 11851 Stainless Steel DZK End with GZ, Notched Tail be used with different gasket materials for high-temperature sterilization processes?

Yes — the DIN 11851 Stainless Steel DZK End with GZ, Notched Tail can be used with different gasket materials for high‑temperature sterilization processes, provided the chosen gasket is rated for the sterilization temperature, pressure and chemical/steam exposure involved. Key points: - The fitting’s operating temperature range depends on the gasket material, so select a gasket specified for high temperatures (e.g., high‑temperature PTFE variants, silicone grades rated for sterilization, or high‑temp perfluoroelastomers like FFKM) rather than standard elastomers that degrade under autoclave/steam conditions. - Ensure the gasket’s chemical compatibility with sterilants (steam, hot water, peroxide, peracetic acid, etc.) and its ability to maintain seal integrity at the coupling’s maximum working pressures (up to 40 bar for DN10–DN40, 25 bar for DN50–DN100, 16 bar for DN125–DN150). - Confirm surface finish (Ra 0.8 µm) and proper assembly torque to avoid extrusion or damage of high‑temp gaskets during repeated cycles. - Validate the complete assembly in the actual sterilization regimen (temperature, duration, cycles) and follow manufacturer recommendations and industry standards for gasket selection and replacement intervals. In short: yes, with appropriate high‑temperature gasket materials and validation for your specific sterilization conditions.
