Frequently Asked Questions
How does a DIN blind flange differ from an SMS blind flange?
The DIN blind uses a DIN 11851 threaded connection with a nut, while the SMS blind follows the SMS (Swedish Milk Standard) connection principle. Both standards are widely used in the food and dairy industry, but DIN is more common in Germany and Eastern Europe, while SMS is prevalent in Scandinavia.
Is the DIN blind suitable for CIP cleaning?
Yes – the polished Ra ≤ 0.8 µm surface and hygienic DIN 11851 construction allow for CIP (cleaning in place) procedures without disassembly.
How quickly can I get it?
We deliver DIN blinds in stock within 1–2 working days throughout Lithuania.
