CONCEPT
Sanitary check valve , also known as “non-return valve”, is designed for use in process piping installations to prevent reverse flow. DERNORD sanitary check valve series is a spring check valve with different connection ends.
WORKING PRINCIPLE
DERNORD sanitary check valve is a type of valve which open or close the valve rely on the medium flow itself. A check valve opens when the pressure below the valve plug exceeds the pressure above the valve plug and the spring force. The valve closes when pressure equalization has been achieved.

I just cleaned one of these that's been in use in our brewery hot water system fro about 4 years (Dec. '19). The SS valve is easy to clean--our water is extremely hard--using acid to remove scale.I just ordered a second one to speed things up when it clogs open again, but having a set or two of the gaskets would be nice. Neither of the two gaskets is a simple flat gasket or Tri-Clamp style, so....

It is designed exactly as I needed, perfect for my application which is to add inert gas to winemaking tanks during transfer.People complaining about this did not make sure the valve meet the requirements of their intended use. If you need a new gasket for the check valve your can just make one.

I have been fabricating my own parts for a novel concept, until I discovered sanitary fittings and Denord!

I needed to stretch the spring a little to get reliable seating. Not an uncommon issue at all. No leaks.

Does its job, but buyers must beware that its internal silicon gasket is almost impossible to remove without damaging it, and it's a very thick non-standard size that cannot easily be replaced, if at all. I couldn't even come close to finding an adequate replacement through McMaster-Carr (red flag #1). I also highly suspect that one of the internal parts (baffle disk?) isn't stainless steel like the rest (red flag #2).
