3. VALVE DESIGN AND FUNCTIONING
The Keott sampling valve is conceived to extract representative samples from a production process
at regular intervals during a batch without compromising the ongoing process. The valve is therefore
designed such that eective cleaning, disinfection/sterilisation and sampling can be carried out regularly
without disturbing the production process.
3.1 Valve body congurations
Valve bodies may be welded to the process equipment or connected by means of one of the standard
connector systems.
Welding congurations encompass the following options:
• Tank welding, ø28 mm
• Pipe welding, 1”
• Pipe welding, NW25
• In-line vertical
• In-line horizontal
Connector congurations encompass the following options:
• Varivent, ø50 mm
• Varivent, ø68 mm
• Clamp ½”
• Clamp 1"; Clamp1", NA-connect, DIN/ASME
• Clamp 2"; Clamp2", NA-connect, DIN/ASME
• Thread
• DIN 11851
The inlet and outlet ports are available in the following congurations:
• Hose Piece (Keott Quick Coupling)
• Mini Tri-clamp
• Thread M16x1.5
• Welding ends (to weld steel tubing on)
All welding/connector options are available with Hose Piece ports. For the other port congurations
only some combinations are standard; but all non-standard combinations are likely to be available “On
request”.
All valve bodies with their various ports are machined in one piece of steel, thus avoiding all crevices and
ssures from screwed or welded parts.

3.2 Valve surfaces and roughness certicate
All Keott valves are electro polished internally using a proprietary technique and each valve has its
individual certicate (Test Report) stating the results of 4 test measurements of the surface roughness in
each of the 2 ports, in the valve chamber and on the outer body surface with product contact.
For obvious reasons, the surface properties of the internal product contact areas of a sampling valve is
much more important from a hygiene perspective than any shiny outside surface appearance. Therefore,
Keott has developed a unique electrode conguration to assure during manufacturing that the internal
surfaces in particular are properly electro polished.
